how may 9-inch-square floor tiles are needed to cover a rectangular floor that measure 12 feet by 15 feet
To find the number of 9-inch square floor tiles needed to cover a rectangular floor measuring 12 feet by 15 feet, we need to convert the measurements to the same units.
1 foot = 12 inches (since there are 12 inches in a foot)
So, the dimensions of the floor in inches are:
Length = 12 feet * 12 inches/foot = 144 inches
Width = 15 feet * 12 inches/foot = 180 inches
Now, let's calculate the area of the floor in square inches:
Area = Length * Width
Area = 144 inches * 180 inches = 25,920 square inches
To find the number of 9-inch square tiles needed to cover the floor, we divide the total area of the floor by the area of each tile.
Area of 1 tile = 9 inches * 9 inches = 81 square inches
Number of tiles = Total area of the floor / Area of 1 tile
Number of tiles = 25,920 square inches / 81 square inches
Number of tiles = 320 tiles
Therefore, you will need 320 9-inch square floor tiles to cover the rectangular floor measuring 12 feet by 15 feet.
To determine the number of 9-inch-square floor tiles needed to cover a rectangular floor measuring 12 feet by 15 feet, we need to convert the measurements to the same units (either inches or feet).
First, let's convert the measurements to inches:
12 feet = 12 x 12 = 144 inches
15 feet = 15 x 12 = 180 inches
To find the area of the rectangular floor, multiply the length by the width:
Area = 144 inches x 180 inches = 25,920 square inches
Each floor tile has an area of 9 inches x 9 inches = 81 square inches.
To determine the number of tiles needed, divide the total area of the floor by the area of each tile:
Number of tiles = 25,920 square inches / 81 square inches = 320 tiles
Therefore, you would need 320 9-inch-square floor tiles to cover the rectangular floor.
(12 * 12) / 9 = 16
(15 * 12) / 9 = 20
16 * 20 = 320 tiles
12 x 15 =180
