Question

A pyramid has a base 16 inches x 16 inches and a slant height of 10 inches.

Hint: You will need to use the Pythagorean theorem to find the altitude.

Volume = ____ cubic in.
Surface area = _____ sq. in.

Answer 1

Set up the equation
8^2+x^2=10^2
64+x^2=100
x^2=36
x=6
The altitude is 6. I put 8 in the equation because that is the distance from the center to the point of the pyramid.
