Question:
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 × 4.5 cm × 4 cm?
Solution:
Volume of the cardboard box $=(120 \times 72 \times 54)=466560 \mathrm{~cm}^{3}$
Volume of each bar of soap $=(6 \times 4.5 \times 4)=108 \mathrm{~cm}^{3}$
Total number of bars of soap that can be accommodated in that box $=\frac{\text { Volume of the box }}{\text { Volume of each soap }}=\frac{466560}{108}=4320$ bars
