Question

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

Answer 1

Volume of the cuboid $=18\times 12\times 9m^3$. Volume of each cube to be cut is $=(3\times 3\times 3)m^3$. Hence number of cubes that can be cut out from the cuboid is
$=\frac{18\times 12\times 9}{3\times 3\times 3}=72.$
