A technical machinist is asked to build a cubical steel tank that will hold 420 L of water. Calculate in meters the smallest possible inside length of the tank. Round your answer to the nearest 0.01 m.

### Answers

Length of the cubic tank = 0.75 m

Step-by-step explanation:

Volume of the tank = 420 L = 0.42

Since the tank is cubic in structure so the volume of the tank is given by

Where a = length of the cubic tank

=0.42

a = 0.75 m

Therefore length of the cubic tank = 0.75 m
