Question

The base of a square pyramid has a side length of 50 centimeters. The slant height is 32 centimeters. Find the surface area. (The formula is: SA= B + 1/2 Pl) B= Area of base; P= Perimeter of base; l= slant height

Answer 1

Given:
side length = 50 cm
slant height = 32 cm

Base Area = (50cm)² = 2,500 cm²
Permeter = 50cm * 4 = 200 cm

Surface area = B + 1/2 PL
SA = 2,500 cm² + 1/2 * 20 cm * 32cm
SA = 2,500 cm² + 320 cm²
SA = 2,820 cm²
