Sagot :

The net square pyramid and its given dimension as shown has a total surface area of 1040 ft².

How to calculate surface area of a square pyramid

Surface area of a square pyramid = A + 1 / 2 ps

where

  • A = area of the base
  • p = perimeter of base
  • s = slant height

Therefore,

A = l²

where

  • l = length = 20 ft

A = 20² = 400 ft²

p = 4l = 4 × 20 = 80 ft

s = 16 ft

Therefore,

Surface area = 400 + 1 / 2 × 80 × 16

Surface area = 400 + 1280 / 2

Surface area = 400 + 640

Surface area = 1040 ft²
