The shorter edges of a 36 cm x 20 cm metalsheet are joined to form the vertical surfaces of a square base prism. What is the volume of the prism? what is the area of metal sheet required to make the top and the bottom of the prism.

height = 20
side length = 36/4 = 9
volume = 9*9*20 cm^3
top = 81 cm^2
bottom = 81 cm^2
81 * 2 = 162 cm^2

Hmmm. Hard to see.
The length is 36 and the width is 20.
If the height of the box is x, then the base would be 18-x. With the other edge width=20, I don't see how the base can be square.

I think it is just folded three times so the short edges can be welded together. No top and bottom yet
