Calculating the Amount of Varnish Needed

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

Amount of Varnish = Area of the Room × Varnish Consumption per Square Meter

Given: - Width of the room = 5m - Length of the room = 4m - Varnish consumption per square meter = 250g

Calculation

First, we calculate the area of the room: - Area = Length × Width - Area = 4m × 5m - Area = 20 square meters

Now, we can calculate the amount of varnish needed: - Amount of Varnish = 20 square meters × 250g/square meter - Amount of Varnish = 5000g

So, 5000g of varnish will be needed to cover the floor in this room.
