Question

A matchbox measures $4$ cm$\times 2.5$ cm $\times 1.5$ cm. What will be the volume of a packet containing 12 such boxes ?

Answer 1

Dimensions of a matchbox (a cuboid) $=4\text{cm}\times 2.5\text{cm}\times 1.5\text{cm}$ $\text{Formula to find the volume of matchbox}=l\times b\times h$
$=(4\times 2.5\times 1.5)$
$=15{\text{cm}}^3$
$\text{Now, volume of 12 such matchboxes}=(15\times 12){\text{cm}}^3$
$=180{\text{cm}}^3$
$\text{Therefore, the volume of 12 matchboxes is}180{\text{cm}}^3.$
