James decided to paint his bedroom. His bedroom walls are 5 metres long and 3 metres high.

To find out how much paint James should buy to paint all the walls of his bedroom, we first need to calculate the total area of the walls.
The total area of the walls can be calculated by multiplying the length of the walls by the height of the walls.
Length of the walls = 5 meters
Height of the walls = 3 meters
Total area of the walls = Length of the walls * Height of the walls
Total area of the walls = 5 meters * 3 meters = 15 square meters
Since 6 litres of paint can cover 10 square meters of the wall, we can calculate how many litres of paint James should buy by dividing the total area of the walls by the coverage of 6 litres.
Number of litres of paint James should buy = Total area of the walls / Coverage of 6 litres
Number of litres of paint James should buy = 15 square meters / 10 square meters = 1.5 litres
Therefore, James should buy 1.5 litres of paint to paint all the walls of his bedroom.
To calculate how much James will pay for the paint, we need to multiply the number of litres of paint by the cost per litre.
Number of litres of paint James should buy = 1.5 litres
Cost per litre = $12.00
Total cost of the paint = Number of litres of paint * Cost per litre
Total cost of the paint = 1.5 litres * $12.00 = $18.00
Therefore, James will pay $18.00 for the paint.
