Question

A contractor finds that 3 gallons of paint will cover 675 sq ft of wall area. How much wall area could be covered with 15 gallons of paint?

Answer 1

To determine the area that can be covered with 15 gallons of paint, knowing that 3 gallos can be used to paint 675ft², first determine the area that can be covered per gallon.

To do so, divide 675 by 3

$\frac{675}{3}=225$

Each gallon of paint covers an area of 225ft²

Next multiply the area per gallon by 15 to determine how much will 15 gallons of paint cover

$225\cdot15=3375$

With 15 gallons of paint you'll be able to cover an area of 3375ft²
