Aright rectangular prism has a volume of 48 ft3. which of the following could not be the dimensions of the prism? l = 2 ft, w = 2 ft, h = 12 ft l = 2 ft, w = 4 ft, h = 6 ft l = 3 ft, w = 2 ft, h = 8 ft l = 4 ft, w = 3 ft, h = 3 ft

For a rectangular prism, V = lwh.
First choice: 2*2*12 = 48, so this is possible.
Second choice: 2*4*6 = 48, so this is possible.
Third choice: 3*2*8 = 48, so this is also possible.
Fourth choice: 4*3*3 = 36, so these cannot be the dimensions of the prism.

The fourth choice is the correct answer.
