Beth is stacking cubes to form a rectangular prism. If each cube has a side length of 1/2 inches, and he has 30 cubes, what is the volume of the prism?

Question

I NEED HELP I DONT UNDERSTAND! :(

Answer 1

If each cube has side 1/2, then the volume of each cube is (1/2)^3 = 1/8

if there are 30 cubes, then the volume of all 30 is 30(1/8) = 30/8 = 3.75 in.^3
