Question

Find the total surface area of the following square pyramid: 4 cm 6 cm SA = [?] cm^2

Answer 1

Answer:

84cm^2

Step-by-step explanation:

The pyramid's SA is the square at the bottom plus the triangles on the side.

The square is 6x6=36.

Per triangle, it's BxH/2. B=6. H=4. Therefore, per triangle has a SA of 12 cm^2.

There are 4 triangles. 48 cm^2 in total for the triangles

36cm^2+48cm^2=84cm^2
