jamie wants to put tiles on the walls and floor of his room( but not on the ceiling). The length of his room is 10 feet,the width of his rooms is 14 feet , and the height is 12 feet. If each tile is 1 foot long and 1 foot wide how many tiles will jamie need ?
the length of room = 10 ft the width = 14 ft the height = 12 ft there are 4 walls and the floor one wall has area = 10*12=120 ft^2 4 walls has area = 4*120=480 ft^2 the floor has area = 10*14=140 ft^2 total area of walls and floor = 480+140= 620 ft^2 - so bc. we know that each tile is 1 foot long and 1 foot wide so what mean an area of 1 ft^2 and the total area equal 620 ft^2 so this mean that Jamie will need 620 tiles
