Question
Becky wants to paint the walls in her bedroom. A gallon of paint will cover 300ft2. She measures the surface to be painted; it's 73,440in2. How many gallons of paint should she buy?
Solution
First, we need to convert the area from square inches to square feet because the coverage of the paint is given in square feet.
1 square foot is equal to 144 square inches.
So, 73,440 square inches is equal to 73,440/144 = 510 square feet.
Next, we need to determine how many gallons of paint Becky needs.
A gallon of paint covers 300 square feet.
So, to cover 510 square feet, Becky would need 510/300 = 1.7 gallons of paint.
Since paint is typically sold in whole gallons, Becky should buy 2 gallons of paint to ensure she has enough to cover her entire bedroom.
