Question

What is the surface area?​

Answer 1

Answer:

0.5 X 15 X 20 = 150m squared

150 X 2 = 300m squared (that's the two triangles done)

25 x 7 = 175m squared (front)

15 X 7 = 105m squared (base)

20 X 7 = 140m squared (back)

now add them all together

300 + 175 + 105 + 140 = 720

SA = 720cm squared

Answer 2

Answer:How do u find the surface area of a cube?

To determine the surface area of a cube, calculate the area of one of the square sides, then multiply by 6 because there are 6 sides. This is the same as solving using the formula SA = 6s2. If you are given the surface area, you can determine the side length by working backwards.
