Answer:
Step-by-step explanation:
Step 3
1. You have that:
- Each gallon of paint covers 400 ft²<span>.
- One side of a wall must be painted and its dimensions are :is 8 meters tall and 40 meters long.
1 ft=0.3048 m
1 ft</span>²=(0.3048 m)²=0.09290 m²
2. Each gallon of paint covers 400 ft<span>², then:
</span>
400 ft²x<span>0.09290=37.16 m</span>²
3. The area of one side of the wall is:
A=8 mx40 m
A=320 m²
4. Therefore, you have:
1 gallon-----37.16 m²
x-----320 m²
x=320x1/37.16
x=8.61 gallons
x≈9 gallons
The answer is: 9 gallons
That looks very hard, keep trying with the steps so yeah
