When using a net, what is the correct formula to find the surface area of a prism with length l, width w, and height h?

Answer 1

The formula to find the surface area of a prism is:

SA = 2(lw + lh + wh)

where SA is the surface area, l is the length, w is the width, and h is the height.

The net of the prism can help you visualize the different faces that make up the surface area. The formula is simply adding up the areas of each face, which includes the top and bottom faces (lw), the front and back faces (lh), and the left and right faces (wh).
