Final answer:
To fill a right rectangular prism, calculate the volume of the prism and divide it by the volume of a cube with edge length of 1/4 inch.
Step-by-step explanation:
To fill a right rectangular prism, we need to calculate the volume of the prism and divide it by the volume of a cube with edge length of 1/4 inch.
The volume of the right rectangular prism can be calculated by multiplying its length, width, and height. Let's say the length of the prism is L, the width is W, and the height is H. So, the volume of the prism is V = L * W * H.
To find the number of cubes needed to fill the prism, we divide the volume of the prism by the volume of a cube with edge length 1/4 inch. So the number of cubes needed is V / (1/4)^3 = 64 * V.
