2: Self-Help Section Surface area for surfers in need Welcome to the self-help section. In this article I will be answering the question, “How do you find the surface area of a complex object?” This will take multiple steps, so bear with me. So here are the answers to your questions. Let’s say that the object is a rectangular prism. The lengths of the bases are 6.1 cm. The width is 2.3 cm. The lengths of the other 2 bases are 4.9 cm. Their widths are 8.2 cm. The height is 9.9 cm. There is a square pyramid on top. The measurement of the square is 5 cm by 5 cm. The triangles’ height is 2.3 cm. The height of the entire pyramid is 9.7 cm. | Charlie Ames
3: First you find the surface area of the prism. To do that you multiply 6.1 by 2.3. You should get 14.0 cm square (if you round to the nearest tenth). Then you multiply by two, so that you account for the other base. If you did that you end up with 28 cm square. Now you multiply the other measurements, 4.9 and 8.2. You should get 40.2 when rounded to the nearest tenth. When you multiply it by two you get 80.4 cm square. Add the two answers together to find the surface area of the prism. You should have gotten 108.4 cm square.
4: Now we will find the surface area of the pyramid. The base is 5x5 which equals 25 square cm. To find the area of the triangle just find one of them and times by 4. So you would multiply 2.3 by 5 (the base length). That equals up to 11.5 square cm. Now divide by 2. That gives us 5.8 rounded up. Multiply 5.8 by four and you will have 23.2 square cm. Add this to the square’s area and you should end up with 48.2 square cm. Now that we have the surface area of both figures we need to add them together so we know the surface area of the whole complex figure. The answers were 48.2 square cm and 68.2 square cm.
5: When you add the two answers together you should end up with the number 116.4 square cm. Thank you for your time and if you need any other kind of help just ask us and we will help.
6: Women in Mathematics Beach Babes in Mathematics | Hilary Rodham Clinton once said that "There cannot be true democracy unless women's voices are heard." Many smart and creative women have contributed to the study of mathematics. Even before Christ there were mathematical happenings, such as when the wife of Pythagoras, Theano, achieved one of her greatest goals, the principal of the "Golden Mean." She did many other things, such as operating the school of Pythagorean after her husband died, and wrote may treatises on mathematics, medicine, and more! This amazing and historic woman lived during the time period during the 6th Centr B.C. | Callan Flynn
7: Obliviously, there were many more women, but one stood out as one of the most hardworking of them all. Hypatia, son of one of the most educated men in Egypt, Theon, was a very smart cookie! Instead of giong on walks, or playing with friends, Hypatia spent her day in a world of education and thought. Although she was taught more than just mathematics, such as world religions, she thrived in astronomy and astrology. Even her students loved and appreciated her works; one recognized her the creation of th eastrolabe. This was a tool used in the study of astronomy. Unfortunately, Hypatia lived during the beginning of Christianity, which faced her with angry mobs. These mobs attacked her, stripped her of her clothing, and killed her with broken pieces of pottery.
8: Winifred received her education from private tutors, and later received her B.A. degree from Wellesley College. After going to Harvard, she then switched schools again, and went to study mathematics and astronomy at Columbia University. After 2 years, she petitioned to get a Ph.D. degree. Even after completing her discoveries including totaling the orbits of the comet of 1883, they refused her application. She then decided to talk to each trustee, gaining their respect, and was soon voted to receive her Ph.D. in mathematics. Go Winifred Edgerton Merrill! | Although these achievements are fascination, nothing can compare with the pride of receiving the first Ph.D. in mathematics. In 1886, Winifred Edgerton Merril became the first American woman to receive a Ph.D. in mathematics. Winifred received her education from private tutors, and later received her B.A. degree from Wellesley College. After going to Harvard, she then switched schools again, and went to study mathematics and astronomy at Columbia University. After 2 years, she petitioned to get a Ph.D. degree. Even after completing her discoveries including totaling the orbits of the comet of 1883, they refused her application. She then decided to talk to each trustee, gaining their respect, and was soon voted to receive her Ph.D. in mathematics. Go Winifred Edgerton Merrill!
9: Another important woman in Mathematics is Sophie Germain. She was born into a wealthy family. She was also born into the early years of the American Revolution. Before she recognized her talents, she was just an average girl living through the American Revolution. When she was 13, she started showing interest in mathematics. Before you know it, she was rummaging through her father’s library. Unfortunately, she was locked in her room until the danger caused by revolts weren’t at high risks. While tired and bored, she read a history book about the legend of Archimede’s death. This legend was about a man named Archimede and how he was very interested in the study of a geometric figure in the sand that he didn’t respond to the soldier talking to him. He was immediately sentenced to death due to the “disrespect given to an authority.” This was all it took to spark her interest. Now she is recognized worldwide as an important mathematician in many areas. She came up with the theory of elasticity and was considered a “math celebrity!”
10: Many careers require math to function. Without math, jobs wouldn’t be able to be done, problems couldn’t be solved, and we would not have many things we have today. Jobs that require math include Engineering, rocket science, and architecture. | Careers Involving Math Fish's Futures | J.D. Coffin
11: Engineering requires a lot of math. To be an engineer, you need to know the numbers and equations to make engines, generators, etc. Without math, engineers would not know how to design new motors or equipment. Math helps engineers, and engineers help the world.
12: Like engineering, architecture needs a ton of math. Architects need the numbers and sizes to make models of the building and the building itself. Architects have to know how big parts of a building need to be to make the building stand up. Without math, buildings would collapse, and be very difficult to make.
13: Lastly, math really helps out rocket science. Math helps design, make, and even help the rocket fly to its designated point. Designing the rocket needs math for its shapes, sizes, and materials. Making the rocket requires math to build the rocket correctly. Math helps the rocket fly by giving numbers that are needed for the rocket to take off, move, and change direction. Without math, we would not have ended many wars or have landed on the moon.
14: Word Problem Charlie Ames | Suppose a sandbox is shaped like a trapezoid. The bottom side is 130 ft and the parallel line is 80 ft. The height is 90 ft. The slanted line is 110 ft. What is the area of the yard? | Answer: 255 ft. squared
15: In the cylinder below, there's lots of candy! Try to find how many there are! Hint: Find the volume of the cylinder! Good Luck!

16: "What is Pi?" A mathematician: "Pi is the ratio of the circumference of a circle to its diameter." A computer programmer: "Pi is 3.141592653589 in double precision." A physicist: "Pi is 3.14159 plus or minus 0.000005." An engineer: "Pi is about 22/7." A nutritionist: "Pie is a healthy and delicious dessert!" | Math Jokes JD Coffin
