Question

Using the net below, find the surface area
of the pyramid.
6 in.
3 in.
3 in.

Answer 1

45 in. squared

Explanation:

First, calculate the area of the four triangles. The formula is (3*6)/2=18/2=9 in. squared. Then, multiply by four (since all the triangles are identical), which gives you 36 in. squared. Lastly, find the area of the square (base) and add it all up. The formula for the area of the square is 3*3=9 in. squared. The final sum is 9 in. squared plus 36 in. squared, which equals to 45 in. squared.
