Finding Volume

100

Volume will always be area of the _______ time ________. If a figure comes to an ________ we divide by 3 (or multiply by 1/3)

base, height, apex

200

Volume of a rectangular pyramid with a base length of 5, a base width of 6, and a height of 9

90 cubic units

300

Two 3D solids that come to an apex

Cone and pyramid
