Use the image to answer the question. How many 1/2-inch cubes would fit inside a right rectangular prism with a length of 2 inches, a width of 1 1/2 inches, and a height of 3 inches? (1 point)
Cubes
The volume of the right rectangular prism can be found by multiplying the length, width, and height together.
Volume = (2 inches) x (1 1/2 inches) x (3 inches)
Volume = 2 inches x 1.5 inches x 3 inches
Volume = 9 cubic inches
Since each 1/2-inch cube has a volume of 1/8 cubic inches (since (1/2 inch) x (1/2 inch) x (1/2 inch) = 1/8 cubic inches), we can now divide the volume of the prism by the volume of one cube to find out how many cubes can fit inside.
9 cubic inches รท 1/8 cubic inches = 72 cubes
Therefore, 72 1/2-inch cubes can fit inside the right rectangular prism.
