Problema Solution
(1).A floor measures 15'-8" x 17'-2".How many 8" by 8" tiles do you need to tile the floor?
(2).A room measures 15'-5" long x 19'-7" wide x 8'-6" high.A gallon of paint covers 350 square ft.How many gallons of paint are needed to paint the walls with two coats of paint?
Answer provided by our tutors
1) number of tiles = 188 *206 / 8*8 = 605.12 rounded we get 606 tile
2) area of walls = 2(15'5" X 8'6" + 19'7" X 8'6") = 595 sq ft.
since each gallon cover 350 sq ft
we get
595/350 = 1.7 gallons
