There are infinitely many possibilities.
Select any positive numbers x and y and let z = 12/(x*y)
Then a rectangular prism with sides measuring x, y and z feet will be
x * y * 12/(x*y) = 12
Since the only restriction on x and y was that they were positive numbers there are an infinite number of choices for each.
So, if x = 10 ft, y = 32 ft then z = 12/320 = 0.0375 ft = 0.45 inches.
A rectangular prism of 12 inches by 7 inches by 4 inches is 336 cubic inches. To get the volume of a rectangular prism, just multiply all the dimensions.
The volume is 27 inches
A rectangular prism 3 inches by 2 inches by 6 inches has a volume of 36 cubic inches.
A rectangular prism with a width of 24 inches a height of 18 inches and a depth of 15 inches has a volume of 6,480 cubic inches.
A rectangular prism with a width of 4 inches a height of 6 inches and a depth of 8 inches has a volume of 192 cubic inches.

A rectangular prism with a width of 4 inches a length of 6 inches and a depth of 13 inches has a volume of 312 cubic inches.
Only if that volume is contained in a rectangular prism.
The volume of a rectangular prism is lwh.5(2)(3)=30 cubic inches
The volume is 96 cubic inches.
432 cubic inches
90 cubic inches.
You cannot calculate it without the length. However, it is possible to get the volume by submerging the prism in water and measuring the volume of the displaced water.
