In a room whose length is 8 m, and the shirenana is 2 m shorter than the length

In a room whose length is 8 m, and the shirenana is 2 m shorter than the length, the floor must be painted. How much paint is needed for this, if 150 g per 1 m2?

The solution of the problem:
1. Determine what is the width of the floor in the room:
8 – 2 = 6.
2. Determine the floor area in the room, knowing that, by definition, the area is equal to the product of length and width:
8 * 6 = 48.
3. Determine how much paint you need for the floor:
48 * 150 = 7200.
Answer: To paint the floor you will need 7200 g of paint, or 7.2 kg.
