Problema Solution
A square pyramid with a base measuring 2 inches per side and a slant height of 2.5 inches. What is the surface area?
Answer provided by our tutors
let
a = 2 in the side length
s = 2.5 the slant height
the surface ares is A = a^2 + 4*(a*s)*(1/2)
A = a^2 + 2*a*s
A = 2^2 + 2*2*2.5
A = 4 + 10
A = 14 in^2
the surface are is 14 square inches.
