Mrs. Cress's table measures 5 ft wide and 8 ft long. She wants to cover the table with 3 in square tiles. How many tiles will she need?
Help Thank you!
is it 2704 tiles?
5 feet = 60 inches
8 feet = 96 inches
60/3 = 20
96/3 = 32
20 * 32 = 640 tiles
To determine the number of tiles Mrs. Cress will need to cover her table, we need to calculate the total area of the table and then divide it by the area of each tile.
First, we need to convert the dimensions of the table into the same unit. Since the width is given in feet and the tiles' area is given in square inches, let's convert the width from feet to inches.
1 foot = 12 inches
Therefore, the table width in inches = 5 ft * 12 inches/ft = 60 inches.
Next, let's convert the length of the table from feet to inches.
The table length in inches = 8 ft * 12 inches/ft = 96 inches.
Now, we can calculate the total area of the table by multiplying its width by its length.
Table area = table width * table length = 60 inches * 96 inches = 5760 square inches.
Since each tile has a square shape, we need to calculate the area of each tile. The tiles are square with a side length of 3 inches, so the area of each tile is 3 inches * 3 inches = 9 square inches.
Finally, to find the number of tiles needed, divide the table area by the area of each tile.
Number of tiles = table area / tile area = 5760 square inches/9 square inches ≈ 640 tiles.
Therefore, Mrs. Cress will need approximately 640 tiles to cover her table.
