Question

A class room is 12 cm long 5m wide 3m high how many pupils should it be used if used for each pupil required 5m cm3 of air space

Answer 1

Length of the room = 12 cm or 0.12 m

Width of the room = 5m

Height of the room = 3m

Volume of the room = l × b × h
= 1.8 m^3

Volume of each child = 5 cm^3 or 0.05m^3


.

maximum no. of children that can occupy the room = volume of room / volume of each child

= 1.8m^3 / 0.05m^3
= 36 children
