Calculate the volume of the prism by first finding the total number of half-unit cubes that will fill it. There are 8 half-unit cubes in every unit cube.

A. Number of half-unit cubes 10 V = 5 cubic units

B. Number of half-unit cubes= 20 V=10 cubic units

C. Number of half-unit cubes= 10 V=2 1/2 cubic units

D. Number of half-unit cubes= 20 V= 2 1/2 cubic units
