Question

Which rectangular solid has greater volume?
(Some of the cubes might be hidden behind other cubes. Try to visualise all of the cubes)

• A. Both the solids have equal volume.
• B.
• C.
• D. Can't be determined

Answer 1

The correct option is C

We can see that there are 3 cubes in each layer of the first rectangular solid.
Volume = length × width × height
= 3 × 1 × 3 = 9 unit cubes

Similarly, we can see that there are 6 cubes in each layer of the second rectangular solid.
Volume = length × width × height
= 3 × 2 × 2 = 12 unit cubes

Therefore, second rectangular solid has greater volume.
