A pyramid has a square bottom, with an area equal to 64 squares meters. the height of the pyramid is 7 inches. if you start at the top of the pyramid and slide all the way down the middle of one of the sides how many feet will you move?
Draw a diagram of a vertical cross-section parallel to one side of the base.
8^2 + 7^2 = d^2
where d is the length down the middle of the face.
