You want to tile a floor with dimensions 3.10m x5.80m the tiles are squares 7.20 in on a side. Approximately how many tiles will you need?

To find out approximately how many tiles will be needed, we need to calculate the area of the floor and then divide it by the area of each tile.

The area of the floor is given by multiplying the length and width:

Area of the floor = 3.10m * 5.80m = 17.98 square meters

The area of each tile is given by squaring the side length:

Area of each tile = (7.20in)^2 = 51.84 square inches

However, we need to convert the area of the tile to square meters to match the units of the floor. There are 0.0254 meters in an inch, so:

Area of each tile = 51.84 square inches * (0.0254m / 1 inch)^2 ≈ 0.0333 square meters

Now we can find the approximate number of tiles needed by dividing the area of the floor by the area of each tile:

Number of tiles needed ≈ Area of the floor / Area of each tile = 17.98 square meters / 0.0333 square meters ≈ 539.04 tiles

Therefore, approximately 539 tiles will be needed.

To find out how many tiles you will need, you need to calculate the total area of the floor and divide it by the area of a single tile.

Step 1: Calculate the area of the floor:
Area of the floor = Length x Width
Area of the floor = 3.10m x 5.80m

Step 2: Calculate the area of a single tile:
Area of a tile = Side length x Side length
Area of a tile = 7.20in x 7.20in

Step 3: Convert the area of the floor and the area of a single tile to the same unit of measurement. Let's convert both to square meters:
1 inch = 0.0254 meters (conversion factor)
Area of the floor = 3.10m x 5.80m
Area of a tile = (7.20in x 0.0254m/in) x (7.20in x 0.0254m/in)

Step 4: Calculate the number of tiles required:
Number of tiles = (Area of the floor) / (Area of a tile)

Now, let's do the calculations:

Area of the floor = 3.10m x 5.80m = 17.98 square meters
Area of a tile = (7.20in x 0.0254m/in) x (7.20in x 0.0254m/in) = 0.13322528 square meters (approximately)

Number of tiles = 17.98 square meters / 0.13322528 square meters ≈ 134.97

Approximately, you will need around 135 tiles to tile the floor.
