+1042 I have to paint one side of a wall. The wall is $15$ meters tall and $60$ meters long. Each gallon of paint covers $400$ square feet. If a foot is approximately $0.3048$ meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?

I have to paint one side of a wall. The wall is $15$ meters tall and $60$ meters long.
Each gallon of paint covers $400$ square feet. If a foot is approximately $0.3048$ meters, then
what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?
1 ft = 0.3048 m therefore 1 m = (1 / 0.3048) ft = 3.2808 ft
H wall = (15)(3.2808) ft = 49.212 ft
L wall = (60)(3.2808) ft = 196.848 ft and so Area wall = (49.212 ft) x (196.848 ft)
= 9687.284 sqft
Paint req'd ––>> (9687.284 sqft) / (400 sqft/gallon) = 24.218 gal
You can't buy just 0.218 of a gallon, so you will need to buy 25 gallons.
