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

Given :
Matchbox is a cuboid having its length (l), breadth (b), height (h) as 4 cm, 2.5cm,and 1.5 cm.

We know that,

Volume of 1 match box
= l x b x h
= (4 x 2.5 x 1.5) \({cm}^{2}\)
= 15 \({cm}^{2}\)

So, the volume Of 12 match boxes is
= Volume of 1 match box x 12
= \( 15 cm^2 x 12 \)
= 180 \({cm}^{2}\)

Therefore, the volume Of 12 match boxes is 180 \({cm}^{2}\)
