Question

Wax is poured into a mold to make a cube shaped candle. The length of each edge of the candle is 9cm. how much wax is needed to make one candle?

A. 9 cubic cm


b 27 cubic cm


c 81 cubic cm


d 729 cubic cm e 6,561 cubic cm

Answer 1

d. 729 cubic cm

Explanation:

The volume is the product of the dimensions. For a cube, the length, width, and height are all the same:

V = LWH

V = (9 cm)(9 cm)(9 cm) = (81 cm²)(9 cm)

V = 729 cm³

729 cm³ of wax is needed to make one candle.
