The Rossi family wants to install new tiles on the floor on their kitchen. The tiles they plan to use are 3 in x 3 in squares. The floor space to be covered is shown in the diagram below with measurements given in feet. How many square tiles will the Rossi family need to cover the kitchen floor?
The measurements are 21 feet, 15 feet, 6 feet, 3 feet, 9 feet, and 6 feet. What I did was that I added all the measurements and it came up to 60. I divide it by 3 and it came up to 20. Is this right?
21+15+6+3+9+6=60
6/3=20
no, this is not correct. you have to multiply all the measurements and then divide is by 9.
Is the answer 6
To calculate the number of square tiles needed to cover the kitchen floor, you first need to calculate the total area of the floor in square feet.
From the given measurements, I assume you have a rectangular-shaped kitchen floor. The dimensions are as follows:
Length = 21 feet, Width = 15 feet.
To find the area of a rectangle, you multiply its length by its width. Therefore, the total area of the kitchen floor can be calculated as:
Area = Length x Width
Area = 21 feet x 15 feet
Area = 315 square feet
Now that you know the total area of the floor, you need to calculate how many tiles will be required to cover it.
The tile size is given as 3 inches x 3 inches, which can be converted to feet by dividing by 12 since there are 12 inches in a foot.
Tile size = 3 inches / 12 = 0.25 feet
To calculate the number of tiles needed, divide the total area of the floor by the area of one tile.
Number of tiles = Total floor area / Area of one tile
Number of tiles = 315 square feet / (0.25 feet x 0.25 feet)
Number of tiles = 315 square feet / 0.0625 square feet
Number of tiles = 5040 tiles
Therefore, the Rossi family will need 5040 square tiles to cover their kitchen floor.
