Questiond. A painter is covering a rectangular wall with dimensions of 4 meters by 3 meters using a special paint that comes in a 50 -liter container. Each liter of paint covers 10 square meters, and the wall requires two coats of paint. After painting this wall, what percent of the paint will be left in the container?
Studdy Solution
STEP 1
What is this asking? How much paint is left over after painting a wall twice, and what percentage of the original container is that? Watch out! Don't forget the wall needs *two* coats of paint!
STEP 2
1. Calculate the wall's area.
2. Calculate the total paint needed.
3. Calculate the remaining paint.
4. Calculate the percentage of remaining paint.
STEP 3
Alright, let's **start** by finding the area of the wall!
We know it's a rectangle, and the area of a rectangle is length times width.
So, we have meters multiplied by meters.
STEP 4
So, the area of the wall is ** square meters**.
STEP 5
Now, remember, we need *two* coats of paint.
So, we multiply the wall's area by :
That's ** square meters** of paint needed in total!
STEP 6
We know that liter of paint covers square meters.
So, to find out how many liters we need, we divide the total area we need to paint by the area covered by one liter:
We need ** liters** of paint.
STEP 7
We started with a **-liter** container and used liters.
To find out how much is left, we subtract:
We have ** liters** of paint left!
STEP 8
To find the percentage, we divide the remaining paint by the original amount and multiply by :
STEP 9
So, there's **** of the paint left in the container!
STEP 10
of the paint is left in the container.
