Question

How many 1-inch cubes do you need to create a cube with an edge length of 5 inches?

Answer 1

Number of 1 inch cubes:

Volume of the 1 inch cubes = 1*1*1 = 1 cubic inches.

Volume of the 5 inch cubes = 5*5*5 = 125 cubic inches.

Number = Volume of the 5 inch cubes / Volume of the 1 inch cubes

= 125 /1 = 125.

125 of the 1-inch cubes.

Answer 2

125

Explanation:

We have to find that How many 1-inch cubes do you need to create a cube with an edge length of 5 inches.

Now,
`Volume of one inch cube=1{*}1{*}1=1 cubic inches`

and
`Volume of five inch cube=5{*}5{*}5=125 cubic inches`.

Therefore,
`Number of 1 inch cubes=(volume of 5inch cubes)/(volume of one inch cube)`

=
`(125)/(1)`

=
`125`

Therefore, we need 125 one inch cubes to create a cube with an edge length of 5 inches.
