Question

godown is in the form of a cuboid of measures 60m × 40m × 30 m. How many cubical boxes can be stored in it if the edge of one cubical box is 2m?

Answer 1

Volume of godown - l×b×h
= 60×40×30
= 72000sq. m
no. of boxes = x
so,
$72000 = {s}^{2} \times x \\ 72000 = {2}^{2} \times x \\ \frac{72000}{4} = x \\ x = 18000$
so 18000 boxes is the answer

Answer 2

volume of godown=lbh
=60×40×30=72000m^3
volume of each cube=a^3
=2×2×2=8m^3
no.of cubical boxes that can fit into the godown=vol.of godown/vol.of cube
no.=
$72000 \div 8 = 9000$
no.of boxes =9000
