Question

Brandon bought a gallon of paint that covers 160 square feet. He wants to paint a wall that is 10 ft. high and 12 ft. wide. Explain whether he will need more than one gallon of paint.

Answer 1

Explanation:

He will not need more than 1 gallon of paint. 10*12 = 120 ft^2

This means that he has 40ft^2 of paint left over in the gallon because it is capable of covering 160ft^2.

Answer 2

• No

Given :

• Height : 10ft
• Width : 12ft
• Total paint : 160ft^2

To find :

• If the paint available is suffice or not

Solution :

Firstly, we'll find the area that needs to be painted.

for that,we are required to know the area of a rectangle which is height times width

• Area = 10ft x 12ft
• Area = 120ft^2

Since , the total amount of paint available can paint 160ft^2 which can paint 40ft^2 more area than the required 120ft^2 area of the wall , Brandon won't be needing more than one gallon of the paint .
