The net of a pyramid is shown below. the net of a square based pyramid, with base edges labeled 4 inches and the height of the triangle labeled 8 inches. the surface area of the solid is square inches.

The answer is 80 square inches. The bottom part is a square. You need to do length times width which is 4 times 4 (the base edges) and it is 16. The formula of area for a triangle is half times length times width. This is 4 times 8 which is 32 and times half or divide by 2 and you get 16 square feet for each triangle face. Multiply 16 by 4 for all triangular faces and you get 64 and add the square surface area (16 squ.feet) and the total surface area is 80.
