Площадь бумаги в рулоне 0.6мх10м=6 м2 
9.72:6=1.62 =2 рулона

Calculation of Wallpaper Rolls Needed

To calculate the number of wallpaper rolls needed to cover a wall, we need to consider the dimensions of the wall and the dimensions of the wallpaper rolls.

Given: - Length of the wall: 3.6 m - Height of the wall: 2.7 m - Width of the wallpaper roll: 60 cm (or 0.6 m) - Length of the wallpaper roll: 10 m

To find the number of rolls needed, we can divide the total area of the wall by the area covered by each roll.

Step 1: Calculate the area of the wall: - Area = Length × Height - Area = 3.6 m × 2.7 m = 9.72 square meters

Step 2: Calculate the area covered by each wallpaper roll: - Area covered by each roll = Width × Length - Area covered by each roll = 0.6 m × 10 m = 6 square meters

Step 3: Calculate the number of rolls needed: - Number of rolls = Area of the wall ÷ Area covered by each roll - Number of rolls = 9.72 square meters ÷ 6 square meters = 1.62 rolls

Since we cannot purchase a fraction of a roll, we need to round up to the nearest whole number. Therefore, we need to buy 2 rolls of wallpaper to cover the wall.
