five quarts of latex enamel paint will cover about 100 square feet of wall surface. how many quart are needed to cover 71 square feet of kitchen wall and 69 square feet of bathroom wall ?
100 / 5 = 140 / x....100 sq ft to 5 qts = 140 sq ft to x qts cross multiply (100)(x) = (140)(5) 100x = 700 x = 700/100 x = 7 qts <==== 7 qts will be needed
