Question

I need help with this.
Find the surface area of each 3D figure below.

Answer 1

Answer:2300 cm2

Explanation:

First you want to divide 350 by 14. You get 25. Now multiply 25 x 26 and then divided by 2. Once you get that answer, multiply that 5 times since there is 5 triangles. Then, add that to the base area. Hopefully this is the right answer. let me know if it is.
