A cuboidal wooden block contains `189\ c m^3` wood. If it be 7cm long and 4.5cm high, find its breadth.

Explanation

Given:
Volume of the cuboidal block is `189 cm^3`.
Length of the cuboidal block is `7 cm`.
Height of the cuboidal block is `4.5 cm`.
Now,
Volume of the cuboidal block`=l\timesbtimesh`
`189=7timesbtimes4.5`
`189=31.5timesb`
`b=6 cm`
Hence, the breadth of the cuboidal block is `6 cm`.
