What is the surface area of this square pyramid.

My answer was 72 ftÂ², but I felt like I might be wrong. If someone could double-check. Thank you

Area of the base = 36

Area of sides

We have 4 equal triangles.....each has a base of 6 and a height of 3....so the area of the sides =

4 * (1/2) (6) (3) = 2 * 6 * 3 = 36

So....the toal area is [ 36 + 36 ] = 72 ft^2

You are correct Agent !!!!!
