Question

Julie and Ryan want to refinish the gym floor at the community center. The rectangular floor is 15.2 meters wide and 25.6 meters long. If each gallon of polyurethane covers about 180 square meters, how many gallons should they buy?

Answer 1

Answer:

3 gallons

Step-by-step explanation:

We need to find the area of the floor first:

25.6*15.2=389.12

Now we divide the surface area by gallons of polyurethane.

389.12÷180=2.161777777777777777777777777777....≈2.16 gallons needed. But OH WAIT! You can't buy 0.16 of a gallon so you need 3 gallons.
