Question

Find the surface of the square pyramid shown below

Answer 1

40

Explanation:

Find the area of one of the triangle faces time that by 4(there is four triangle faces) and then add that by the area of the square face(16). 4*4=16

Area of triangle face: 6*4=24(triangle faces)+16(Square face)=40

Answer 2

40

Explanation:

The area of the base is 4 * 4 (because it's a square) = 16

The area of one side is 4 * 3 * 1/2 = 6, but there are 4 sides, so the combined area of the sides is 6 * 4 = 24

16 + 24 = 40
