How many 12-inch cubes would fit inside a right rectangular prism with a length of 2 inches, a width of 112 inches, and a height of 3 inches?

The volume of the right rectangular prism is length x width x height = 2 x 112 x 3 = 672 cubic inches.

To find how many 12-inch cubes would fit inside, we need to divide the volume of the prism by the volume of one cube. The volume of a 12-inch cube is 12 x 12 x 12 = 1728 cubic inches.

Dividing 672 cubic inches by 1728 cubic inches gives us approximately 0.389. So we can fit about 0.389 of a 12-inch cube inside the prism.

Since we can't have a fraction of a cube, we need to round down to the nearest whole number. Therefore, we can fit 0 whole 12-inch cubes inside the prism.

Answer: 0.
