Tim and tom are painters. tim and tom use a liters of paint on a large shipping crate. if the next crate they need to paint is similar but has twice the volume, how much paint should they plan on buying? use the given information to provide the desired estimate. if necessary, enter the answer to the nearest hundredth.

This is the concept algebra.
Volume of of paint that is required to paint  large shipping crate is a liters.
suppose the volume of this crate is x cubic units.
The volume of the next crate to be painted will be 2x cubic units.
Hence the amount of paint required to paint the crate will be:
(volume of bigger crate)/(volume of smaller crate)×(volume of liters required to paint the first crate)
=(2x)/(x)×a
=2a liters
To paint the new crate 2a liters of oil is needed.
