Calculating Paint Needed for a Rectangular Room

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

Area = Length × Width

Given: - Length of the room = 6 m - Width of the room = 5 m - Paint consumption rate = 280 grams per square meter

Calculation

Using the given length and width, we can calculate the area of the room:

Area = 6 m × 5 m = 30 square meters

Now, to find the amount of paint needed, we can use the paint consumption rate:

Amount of paint = Area × Paint consumption rate

Amount of paint = 30 m² × 280 g/m² = 8400 grams

So, 8400 grams of paint would be needed to cover the floor of this room.
