On a scale drawing of Caleb's house, the four bedroom walls each measure 10 inches wide by 6 inches tall. The scale of the drawing is 1 inch = 1.5 feet. Caleb will paint all four walls. If a gallon of paint covers 250 square feet, how many gallons of paint will Caleb need?

Answer:

Approximately 2 gallons of paint are required to paint four bedroom walls

Step-by-step explanation:

Dimensions of the four bedroom walls = 10 inches wide by 6 inches tall

As 1 inch = 1.5 feet,

10 inches [tex]=10(1.5)=15[/tex] feets

6 inches [tex]=6(1.5)=9[/tex] feets

Dimensions of the four bedroom walls = 15 feets wide by 9 feets tall

Area of one wall = product of the dimensions [tex]=15(9)=135[/tex] square feets

Area of four walls = [tex]4(135)=540[/tex] square feets

Area of four walls covered by a gallon of paint = 250 square feets

So,

Amount of paint required = [tex]\frac{540}{250}=2.16[/tex]

That is approximately 2 gallons of paint are required to paint four bedroom walls
