Question

Tim and tom use a liters of paint of a building. If the next building they need to paint has a similar shape but twice the volume, how much paint should they plan on buying?

Answer 1

The capacity of the paint gives the volume of the building.

If the volume of the building to be painted doubles, the paint capacity also doubles.

Given that the volume of the second building is twice the volume of the first building, the capacity of the paint will also double.

The volume of the paint is thus :

2 × a litres.

= 2a litres
