Question

An interior painter is painting a wall that is 8 feet by 14 feet. He needs to determine how much paint he will need for the job.

If a pint will cover 40 square feet, how many pints of paint are needed to paint the wall?

Answer 1

Compute the area

8 ft x 14 ft =112ft^2
Then,
If one pint = 40 ft^2

112ft^2/40ft^2 = 112/40 pints (calculate this in your calculator)

Answer 2

To determine how many pints of paint are needed to paint the wall, we need to calculate the area of the wall and then divide it by the coverage of one pint.

First, let's calculate the area of the wall by multiplying its length by its width.
Area of the wall = length × width = 8 feet × 14 feet = 112 square feet.

Next, we divide the total area of the wall by the coverage of one pint of paint, which is 40 square feet per pint.
Number of pints needed = Area of the wall ÷ Coverage per pint = 112 square feet ÷ 40 square feet/pint.

Now, let's calculate the result:
Number of pints needed = 2.8 pints.

Since we can't have a fraction of a pint, we would need to round up to the nearest whole number.

Therefore, the interior painter would need 3 pints of paint to paint the wall.

Answer 3

To determine how much paint is needed to paint the wall, you need to calculate the total square footage of the wall and divide it by the coverage area of one pint of paint. Here's how you can do it step-by-step:

Step 1: Calculate the total square footage of the wall. To do this, multiply the length (8 feet) by the width (14 feet).
8 feet x 14 feet = 112 square feet

Step 2: Determine how many square feet one pint of paint can cover. According to the given information, one pint of paint can cover 40 square feet.

Step 3: Divide the total square footage of the wall by the coverage area of one pint of paint to find out how many pints are needed. Divide 112 square feet by 40 square feet.
112 square feet ÷ 40 square feet = 2.8 pints

Therefore, the painter will need approximately 2.8 pints of paint to paint the wall. Since pint is not a unit that can be divided, the painter will need to purchase 3 pints of paint to have enough for the job.
