PLEASE HELP! 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 unite cube.

A. Number of half-unit cubes = 20 V = 10 cubic units
B. Number of half-unit cubes = 20 V = 2 1/2 cubic units
C. Number of half-unit cubes = 10 V = 5 cubic units
D. Number of half-unit cubes = 10 V 2 1/2

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
