A wall is 300 square feet. A gallon of paint covers 110 square feet. What is an appropriate conversion factor to help determine how many gallons of paint will be needed to paint the wall?

Answer 1

Answer: 2.723 gallons

Step-by-step explanation:

For this question, we have to find an appropriate conversion factor to help determine how many gallons of paint will be needed to paint the wall.

$Since a gallon of paint covers 110 square feet \\So, \frac{1 \text { gallon }}{110 \text { sq.feet }} will be the conversion factor\\ \begin{aligned}\therefore & \frac{1}{100} \times 300 \text { gallons } \\&\approx2.723 \text { gallons }\end{aligned}$
