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 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?

Jamie will need 716 tiles.

Step-by-step explanation:

Jamie wants to put tiles on the walls and floor of his room.

Length of his room = 10 feet

Width of his room = 14 feet

Height of the room = 12 feet.

Area of the floor = Length × width

                            = 10 × 14 = 140 feet²

As the room is rectangular shape so area of wall on width side is more than the area on length side.

Area of the wall on length side = length × height

     =  10 × 12 = 120 feet²

There are two walls of same length = 120 × 2 = 240 feet²

Area of  wall on width side  =  14 × 12 = 168 feet²

Area of two opposite walls of same width = 168 × 2 = 336 feet²

Total area where Jamie wants to put tiles = 140 + 240 + 336

                                                                     = 716 feet²

Each tile is 1 foot long and 1 foot wide, Hence Jamie will need 716 tiles.
