Volume of a rectangular prism with dimensions 2 by 3 by 4 is:

• A. 18
• B. 24
• C. 12
• D. 6

Answer: (B)

Volume is found by multiplying the three edge lengths that make up the prism. With edges 2, 3, and 4, multiply all three: 2 × 3 × 4 = 24. This uses every dimension, which is what fills the space inside the prism, so the volume is 24 cubic units. If you only multiply two dimensions, you’re getting a base area or a partial product, not the full volume, which is why those other numbers don’t fit. The order of multiplication doesn’t matter, so 4 × 3 × 2 also gives 24.
