Agallon of paint will cover about 350 square feet of space. you are painting 3 halls of a school. ignoring the doors, the halls are 10 feet tall and 125 feet long. you buy 11 gallons of paint. did you buy enough paint? if not, why?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
