Question

how many 1-inch cubes do you need to fill a cube that has an edge length of 1 foot?How can this result help you convert a volume from cubic inches to cubic feet? from cubic feet to cubic inches?

Answer 1

1 foot = 12 inches

Number of one-inch cubes that can fit in length wise = 12 

Number of one-inch cubes that can fit in width wise = 12 

Number of one-inch cubes that can fit in height wise = 12 

Total one-inch cube = 12³  [or 12 x 12 x 12]

Total one-inch cube = 1728 

Inch cube to foot cube:
1) multiplying it by 12
2) cube it.

Foot cube to Inch cube:
1) cube root it
2) divide by 12
