Help please? This is my homework for today so yea

Answer:
72 in^3
36 in^3
80 in^3
54 in^3
Step-by-step explanation:
Basically, all your doing is multiplying each of the 3 numbers together since the formula for the volume of a rectangular prism is L x W x H.
4 × 3 = 12 × 6 = 72
6 × 3 = 18 × 2 = 36
4 × 5 = 20 × 4 = 80
2 × 9 = 18 × 3 = 54
Hope this helps !! Have a good day! :)
