Question

Find the surface area of a pyramid with a square base with dimensions 100 mm by 100 mm and height of 75 mm.

Answer 1

We need the pythagorean theorem to calculate s:

s = sqrt[(0.5*b)^2 + h^2]
= sqrt[(0.5*100)^2 + 75^2]
= 90.139 mm

Therefore, A = 2(100)(90.139) + (100)^2
A = 28,027.8 mm^2
