So one the triangle face of the pyramid has an area of 27 square feet ( 9 x 6/ 2)
Multiply that by 4 because there are 4 faces of triangles (27 x 4 = 108 square feet)
The area of the square base is 36, we get that by multiplying 6 by 6 (since the square has equal sides.
Add 108 and 36 then you get 144 square feet
