5*2=10 кв.м 300*10=3000 г=3 кг 3/3=1 банка

Answer 2

Calculating Paint Needed for the Floor

To calculate the amount of paint needed to cover the floor, we can use the formula:

Total paint needed = Area of the floor * Amount of paint per square meter

Given: - Length of the corridor = 5 meters - Width of the corridor = 2 meters - Amount of paint per square meter = 300 grams

Calculating the Area of the Floor

The area of the floor can be calculated using the formula:

Area = Length * Width

Substituting the given values: - Length = 5 meters - Width = 2 meters

Area = 5 * 2 = 10 square meters

Calculating the Total Paint Needed

Using the formula mentioned earlier:

Total paint needed = 10 square meters * 300 grams/square meter

Total paint needed = 3000 grams

Calculating the Number of Paint Cans Needed

Given: - Amount of paint per can = 3 kilograms = 3000 grams

To find the number of cans needed, we can divide the total paint needed by the amount of paint per can:

Number of cans needed = Total paint needed / Amount of paint per can

Number of cans needed = 3000 grams / 3000 grams per can

Number of cans needed = 1 can

Therefore, you would need to buy 1 can of paint to cover the floor of the corridor.
