Calculating Paint Needed for Floor

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

Amount of paint (in grams) = area of the floor (in square meters) × paint needed per square meter (in grams)

Given that the floor has a width of 7 meters and a length of 9 meters, we can calculate the area of the floor:

Area = width × length

Area = 7m × 9m = 63 square meters Now, using the given paint requirement of 200 grams per square meter, we can calculate the total amount of paint needed:

Amount of paint = 63 square meters × 200 grams/square meter = 12600 grams

So, 12600 grams of paint will be needed to cover the floor.
