A match box measure `4 c m xx2. 5 cm xx 1. 5 c m` . What will be the volume of a packet containing 12 such boxes?

Explanation

Solution
Given:

Matchbox dimensions
`=4cm xx 2.5cm xx 1.5cm`
length `=4cm`,breadth`=2.5cm` & height`=1.5cm`
So,
Volume of cuboid `=(l xx b xx h)`
Hence we conclude,
Volume of one matchbox = Volume of cuboid
Volume of one matchbox `=4 xx 2.5 xx 1.5=15cm^3`
Volume of a packet containing `12` such boxes `= 12 x` volume of one match box
`(12 xx 15)cm^3 =180cm^3`
Hence, the volume of a packet containing `12`
such boxes`=180cm^3`
