What is the lateral surface area of a pyramid

Question

The pyramid shown has a square base that is 32
centimeters on each side. The slant height is 24
centimeters. What is the lateral surface area?

Answer 1

So the lateral surface of the pyramid is composed of 4 triangles, each of which has a base of 32 cm and a height of 24 cm.

 

A = 4(1/2)bh

A = 4(1/2)(32 cm)(24 cm)

A = 1536 cm²
