I don't know how to solve surface area

1 answer:

5 0

Find the area of each face of the figure. So, find the area of one of the triangular faces and multiply it by 2 because there are 2 of them. Then find the area of the front rectangle, the back rectangle, and the bottom rectangle. Add all of these areas up to get the surface area.
