how many vinyl tiles are needed to tile a kitchen measuring 10 1/2ft by 18ft if the tiles equal 25cm on each side

1 ft = 30.48 cm

10 1 / 2 ft = 10.5 * 30.48 = 320.04 cm

18 ft = 18 * 30.48 = 548.64 cm

320.04 * 548.64 ) / ( 25 * 25 ) =

175586.7456 / 625 = 280,93879296

Your answer of 280.9 tiles might work if all the scraps could be fitted together as needed. However, if we assume that no scrap can be reused, then

10.5 ft = 320 cm = 13 tiles wide
18 ft = 548cm = 22 tiles long

So, a better estimate would probably be 13*22 = 286 tiles.

Naturally, if some scraps could be made to fit in, then the true usage would be between 281 and 286

To find out how many vinyl tiles are needed to tile a kitchen measuring 10 1/2ft by 18ft, we need to convert the measurements into the same unit.

First, let's convert the width of the kitchen to inches:
10 1/2 ft * 12 inches/ft = 126 inches

Then, let's convert the length of the kitchen to inches:
18 ft * 12 inches/ft = 216 inches

Next, let's convert the size of the vinyl tiles to inches:
25 cm * 0.39370 inches/cm = 9.8425 inches

To calculate the area of the kitchen surface, we multiply the width by the length:
Area = 126 inches * 216 inches = 27,216 square inches

Now, let's find out how many tiles fit in the kitchen area:
Number of tiles = Area / Tile area

Since the tiles are square, the tile area equals the length of one side squared:
Tile area = 9.8425 inches * 9.8425 inches = 96.875625 square inches

Number of tiles = 27,216 square inches / 96.875625 square inches ≈ 280.71 tiles

Therefore, approximately 281 vinyl tiles are needed to tile the kitchen.

To determine the number of vinyl tiles needed to tile a kitchen, you'll need to follow these steps:

1. Convert the dimensions of the kitchen into the same unit as the size of the tiles. In this case, since the tile size is given in centimeters (cm), you need to convert the measurements of the kitchen into centimeters as well.

10 1/2 feet = (10 * 12) + (1/2 * 12) = 126 + 6 = 132 inches
132 inches = 132 * 2.54 = 335.28 cm (rounded to the nearest centimeter)

18 feet = 18 * 12 = 216 inches
216 inches = 216 * 2.54 = 548.64 cm (rounded to the nearest centimeter)

So, the kitchen measures approximately 335.28cm by 548.64cm.

2. Calculate the area of each vinyl tile. Since the tiles are square and have a length of 25cm on each side, the area of each tile is calculated by multiplying the side length by itself:

Area of each tile = 25cm * 25cm = 625 square cm

3. Determine the total number of tiles needed by dividing the total area of the kitchen by the area of each tile:

Total number of tiles = (Area of the kitchen) / (Area of each tile)

Total number of tiles = (335.28cm * 548.64cm) / 625 square cm

Total number of tiles = 183924.07 square cm / 625 square cm

Total number of tiles (rounded up to the nearest whole number) = 295 tiles

Therefore, approximately 295 vinyl tiles are needed to tile a kitchen measuring 10 1/2ft by 18ft, assuming the tiles are 25cm on each side.
