Question

How many $3meter$ cubes can be cut from a cuboid measuring $18m\times 12m\times 9m$?

• A. $70$
• B. $75$
• C. $76$
• D. $72$

Answer 1

The correct option is D $72$

Volume of cuboid $=18\times 12\times 9=1944m^3$

Volume of a cube $=3^3=27m^3$

Therefore,

No. of cubes $=\frac{\text{Volume of cuboid}}{\text{Volume of 1 cube}}=\frac{1944}{27}=72\text{cubes}$
