Answer:
3.2 gal
Step-by-step explanation:
given:
825 sq ft require 1 gal,
hence the unit rate for the paint coverage is,
= 1 gal / 825 sq ft
= (1/825) gal per square foot
given that we need to cover 2640 sq. ft, this will require
2640 sq.ft x unit rate for paint coverage
= 2640 sq.ft x (1/825) gal per square foot
= 3.2 gal
