ANSWERS: (1) V = L x W x H
V = 15 feet x 12 feet x 9 feet
V = 1,620 cubic feet
(2) V = L x W x H
V = 4 1/2 feet x 4 feet x 3 1/2 feet
V = 9 x4 x 7

V = 63 cubic feet
VOLUME OF A CUBE
A cube is a special form of rectangular solid; its length, width, and height are
all equal. All of its six sides are squares and all of its edges are equal in
length.
You can use the formula V = L x W x H to find the
volume of a cube. However, since the length, width,
and height will always be equal in length, the
formula can be written:
V = S3 or the formula is read:
"Volume = 1 side cube"
and S3 means S x S x S
