(05.07) 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. numerical answers expected! answer for blank 1:

We look for the area of the base.
 Square:
 A1 = (4) * (4) = 16 in ^ 2
 We look for the area of the triangles of the pyramid:
 A2 = (1/2) * (4) * (8) = 16 in ^ 2
 The surface area of the pyramid is:
 A = A1 + 4 * A2
 Substituting values:
 A = 16 + 4 * (16)
 A = 80 in ^ 2
 
 The surface area of the solid is 80 square inches

The first one is 2/3the second is 1/160the third is 4/125
