How many cube-shaped boxes with 12-inch edges can fit into a box thatis 4

DochEvi [55]

Answer:

Step-by-step explanation:

First recall that:

1 inch=12 feet

The volume of cube-shaped boxes with 12-inch edges is 1 cm³

The volume of a box that is 4

feet tall, 4 feet long, and 5 feet wide is

given by:

$Volume = lwh$

We substitute l=4ft, w=5ft and h=4ft

To obtain:

$Volume = 4 \times 4 \times 5 = 80 {ft}^{3}$

Therefore 80 cube-shaped boxes with 12-inch edges can fit into a box that is 4

feet tall, 4 feet long, and 5 feet wide.
