Question

A cuboid has dimensions $5cm\times 4cm\times 2cm$. Number of cubes of 2 cm side that can be cut from cuboid is :

• A. 18
• B. 5
• C. 10
• D. None of these

Answer 1

The correct option is C 10

Volume of cuboid $=5\times 4\times 2=40{cm}^3$

Volume of cube $={\left(2\right)}^3=8{cm}^3$

$\therefore$ Number of cubes $=\frac{Volumeofcuboid}{Volumeofcube}=\frac{40}{8}$

Number of cubes $=5$
