Question

A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 212 cm.

The prism is filled with cubes that have edge lengths of 12 cm.



How many cubes are needed to fill the rectangular prism?

Enter your answer in the box.

To fill the rectangular prism,
cubes are needed.

Answer 1

140

Explanation:

Simple, do 2.5x7x4/.5 and you'll get 140

Answer 2

number of cubes = 70 / 0.125

number of cubes = 560 cubes

Explanation:

first solve the volume of the rectangular prism

V = l x w x h

where l is the length

w is the width

h is the height

V = 7 x 4 x 2.5

v = 70 cu cm

then solve the volume of the box

v = e^3

v = 0.5^3

v = 0.125
