The number of pieces The customer will need actually is 38 tiles
The number of tiles in boxes the customer will buy is 45 tiles
Step-by-step explanation:
To solve the problem we will do these steps
1. Change the dimensions of the room from feet to inches
2. Calculate the area of the room
3. Calculate the area of one tile
4. Divide the area of the room by the area of the tile to find the number
of tills
5. Divide the number of tiles by the number of pieces in one box
to find the number of boxes he will need to buy
∵ The dimensions of the room are 8 feet by 9 feet 6 inches
∵ 1 foot = 12 inches
∴ 8 feet = 8 × 12 = 96 inches
∴ 9 feet 6 inches = 9 × 12 + 6 = 108 + 6 = 114 inches
∴ The dimensions of the sun room are 96" by 114"
The area of a rectangle is length × width
∵ Area of the room = 96 × 114 = 10944 inches²
∵ The dimensions of a tile are 12" by 24"
∴ Area of a tile = 12 × 24 = 288 inches²
∵ The number of tiles = Area room ÷ area tile
∴ The number of tiles = 10944 ÷ 288 = 38 tiles
The number of pieces The customer will need is 38 tiles
V.I.N:
The tiles come in boxes each box contains 9 pieces
∵ 38 ÷ 9 = 4.22
∴ He will need to buy 5 boxes with 45 tiles
The number of tiles in boxes is 45 tiles
