A right rectangular prism has edges of 2 1/4 in, 1 1/2 in and 1 1/2 in. How many cubes with lengths of 1/4 in would be needed to

Zielflug [23.3K]

The volume of a rectangular prism is (length) x (width) x (height).

The volume of the big one is (2.25) x (1.5) x (1.5) = 5.0625 cubic inches.

The volume of the little one is (0.25)x(0.25)x(0.25)= 0.015625 cubic inch

The number of little ones needed to fill the big one is

 (Volume of the big one) divided by (volume of the little one) .

 5.0625 / 0.015625 = 324 tiny cubies

=================================================

Doing it with fractions instead of decimals:

The volume of a rectangular prism is (length) x (width) x (height).
Dimensions of the big one are:

 2-1/4 = 9/4
 1-1/2 = 3/2
 1-1/2 = 3/2

 Volume = (9/4) x (3/2) x (3/2) =

 (9 x 3 x 3) / (4 x 2 x 2) =

 81 / 16 cubic inches.

As a mixed number: 81/16 = 5-1/16 cubic inches

Volume of the tiny cubie = (1/4) x (1/4) x (1/4) = 1/64 cubic inch.

The number of little ones needed to fill the big one is

 (Volume of the big one) divided by (volume of the little one) .

 (81/16) divided by (1/64) =

 (81/16) times (64/1) =

 5,184/16 = 324 tiny cubies.
