Question

The pyramid shown had a square base and congruent triangular faces. Calculate the surface area of the pyramid.

Answer 1

Square base means the bottom is 6 x 6 = 36 in^2
There are four triangular sides whose area can be measured by using (b x h)/2, which is (6 x 5)/2 = 15 in^2 per side, so 15 x 4 = 60 in^2, plus the bottom which makes a total of 96 in^2
