Answer: 3.5 meters
Step-by-step explanation:
Given : The volume of a new pond = [tex]7.35\ m^3[/tex]
The length of a new pond = 4.2 m
The depth of the pond = 50 cm =0.5 m
Let the width of the pond be 'w'.
The volume of cuboid is given by :_
[tex]V=l\times h\times w\\\\\Rightarrow\ 7.35=4.2\times0.5\times w\\\\\Rightarrow\ w=\dfrac{7.35}{0.5\times4.2}\Rightarrow\ w=3.5[/tex]
Hence, the width of the pond = 3.5 meters
