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

The volume of the right rectangular prism can be calculated using the formula V = lwh, where l is the length, w is the width, and h is the height.

V = 2 inches x 1.5 inches x 3 inches
V = 9 cubic inches

Since each 1/2 inch cube has a volume of 0.5 cubic inches (0.5 x 0.5 x 0.5), we can divide the total volume of the prism by the volume of each cube to find out how many 1/2 inch cubes would fit inside.

9 cubic inches / 0.5 cubic inches = 18 cubes

Therefore, 18 one-half inch cubes would fit inside the right rectangular prism.
