A quart of paint will cover 3/4 of a wall . how many quarts are required to cover four walls of the same size
set up a simple ratio ...
1/x = (3/4) / 4
(3/4)x = 4
3x = 16
x = 16/3
I will take 5 1/3 quarts
You will need to buy 6 quarts, (best bought as 1 gallon and 2 quarts)
or, (by the 3 step process)
3/4 wall takes 1 quart
one wall takes 1 / (3/4) quarts or 4/3 quarts
4 walls take 4(4/3) or 16/3 quarts , same as above
To find out how many quarts of paint are required to cover four walls, we need to calculate the total area of the four walls and then determine how many quarts are needed to cover that area.
Given that a quart of paint covers 3/4 of a wall, it means that 1 quart covers 3/4 of the total area. Therefore, we can say that 1 quart covers (3/4) of the total area.
For four walls, the total area is four times the area of one wall. So, we need to multiply the area of one wall by 4.
Let's assign a value for the area of one wall. For this example, let's say the area of one wall is A.
The total area of four walls is 4*A.
Now, we know that 1 quart covers (3/4) of the total area, so we can set up a proportion:
1 quart / (3/4 of the area) = X quarts / (4 times the area)
To solve for X (the number of quarts required), we can cross multiply and solve for X:
1 quart * (4 times the area) = X quarts * (3/4 of the area)
4A = 3/4 * 4A
4A = 3A
So, X = 3 quarts.
Therefore, you would need 3 quarts of paint to cover four walls of the same size.
To find out how many quarts are required to cover four walls of the same size, we need to determine the total area of the four walls and then calculate the amount of paint needed based on the given coverage.
Step 1: Calculate the total area of the four walls
If a quart of paint covers 3/4 of a wall, it means that 1 quart can cover 3/4 of the area of one wall. So, to find the total area of the four walls, we multiply the area of one wall by 4.
Step 2: Calculate the amount of paint needed
To calculate the amount of paint needed, we divide the total area of the four walls by the coverage per quart.
Let's assume the area of one wall is W square units.
Total area of four walls = 4 * W square units
Amount of paint needed = (Total area of four walls) ÷ (Coverage per quart)
= (4 * W) ÷ (3/4) quarts
Simplifying the expression:
Amount of paint needed = (4 * W) * (4/3) ÷ 1 quarts
= (16W) ÷ (3) quarts
Therefore, the number of quarts required to cover four walls of the same size is (16W) ÷ (3) quarts.
