Question
A matchbox measures 4 cm × 2.5 cm × 1.5 cm. What will be the volume of a packet containing 12 such boxes?
Solution
Matchbox is a cuboid having its length (l), breadth (b), height (h) as 4 cm, 2.5 cm, and 1.5 cm.
Volume of 1 match box = l × b × h
= (4 × 2.5 × 1.5) cm3 = 15 cm3
Volume of 12 such matchboxes = (15 × 12) cm3
= 180 cm3
Therefore, the volume of 12 matchboxes is 180 cm3.
