james decided to paint his bedroom.his bedroom wall are 5 metres long and 3 metres high.if 6 metres of paint can cover 10 square metres of the wall,how much paint should james buy to paint all the walls of his bedroom.

Answer 1

Assuming you meant 6 liters of paint, then he needs

5m*3m * 6L/10m^2 = 9L

That's for one wall. No idea how many walls there are.

Answer 2

Im very confused could you please give me the break down/formula of how you have got this answer.

Answer 3

Since you gave the dimension of only one wall, let's assume that the room is square.
As Steve showed in his calculation, one wall has an area of 5x3 or 15 m^2
So 4 walls have an area of 60 m^2

if 6 litres cover 10 m^2
1 L will cover 10/6 or 5/3 m^2

number of litres of paint = 60/(5/3) = 36 L

Notice Steve gave you 9 L for 1 wall, so for four walls it is .....
