Question

Ada stacks cubes of volume $1$ cu m to make two different solids, A and B. Compare their volumes and select the option with the correct answer.

• A. Solid A has a greater volume
• B. Solid A and B have equal volumes
• C. Solid B has a greater volume
• D. Cannot compare as they have different shapes

Answer 1

The correct option is A Solid A has a greater volume

Volume of each cube $=1$ cu m
Number of cubes in Solid $A=2\times 2\times 3=12$
Volume of Solid $A=12\times 1=12$ cu m

Number of cubes in Solid $B=1\times 2\times 5=10$
Volume of solid $B=10\times 1=10$ cu m

Since $12$ cu m $>10$ cu m, Solid A has a greater volume.
Hence, Option A is correct.
