96:6=16 плиток

Answer 2

Calculating the Number of Tiles Needed to Cover the Floor

To calculate the number of tiles needed to cover the floor, we can use the formula:

Number of tiles = Total area of the floor / Area of each tile

Given: - Length of the room = 12 m - Width of the room = 8 m - Area of each tile = 6 sq. dm

Calculation

First, we need to calculate the total area of the floor: - Total area = Length * Width - Total area = 12 m * 8 m - Total area = 96 sq. m

Now, we convert the total area to square decimeters (1 sq. m = 10000 sq. dm): - Total area = 96 sq. m * 10000 sq. dm/sq. m - Total area = 960000 sq. dm

Now, we can calculate the number of tiles needed: - Number of tiles = Total area / Area of each tile - Number of tiles = 960000 sq. dm / 6 sq. dm - Number of tiles = 160000

Therefore, the number of tiles needed to cover the floor is 160000.
