Hello, benny92000!

If a rectangular prism has faces with areas of 8, 10, and 20 units squared,

then what is its volume? .The answer is 40.

How do I know which sides (length, width, height) correspond to which given area?

We don't need that information . . .

We have: .Code:*-----------* / /| / / | H *-----------* | | | * | | / | |/ W *-----------* L

Multiply the equations: .

Hence: .

Therefore the volume is: .
