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: .
