Question:
A beam of wood is 5 m long and 36 cm thick. It is made of 1.35 m3 of wood. What is the width of the beam?
Solution:
Volume of the beam $=1.35 \mathrm{~m}^{3}$
Length $=5 \mathrm{~m}$
Thickness $=36 \mathrm{~cm}=0.36 \mathrm{~m}$
Width $==\frac{\text { volume }}{\text { thickness } \times \text { length }}=\frac{1.35}{5 \times 0.36}=0.75 \mathrm{~m}=75 \mathrm{~cm}$
