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.
Im very confused could you please give me the break down/formula of how you have got this answer.
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 .....
To find out how much paint James should buy to paint all the walls of his bedroom, we need to calculate the total area of the walls first.
First, let's find the area of each wall. The bedroom has four walls, and they all have the same dimensions.
The length of each wall is 5 meters, and the height is 3 meters.
So, the area of each wall is calculated by multiplying the length by the height:
Area of each wall = Length × Height = 5 meters × 3 meters = 15 square meters
Since there are four walls, we need to multiply the area of one wall by four to get the total area of all the walls:
Total area of all walls = Area of one wall × Number of walls = 15 square meters × 4 = 60 square meters
Now, we know that 6 meters of paint can cover 10 square meters of the wall.
To find out how much paint James should buy, we need to divide the total area of all the walls by the area covered by 6 meters of paint:
Amount of paint = Total area of all walls / Area covered by 6 meters of paint
Amount of paint = 60 square meters / 10 square meters
Amount of paint = 6 meters
James should buy 6 meters of paint to paint all the walls of his bedroom.
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.
