A cardboard box is 1.2 m long, 72 cm wide and 54 cm high. How many bars of soap can be put into it if each bar measures 6 cm x 4.5 cm x 4 cm?
We know that,
Volume of cuboid = Length × Breadth × Height
Firstly, we have to find out volume of cardboard box
Volume of cardboard box = 120 × 72 × 54
= 466560 cm3
Now,
Volume of each bar of soap = 6 × 4.5 × 4
= 108 cm3
Therefore,
Total number of bars of soap that can be accommodated in that box = 
= 
= 4320 bars
