Answer 1

$135.92

Explanation:

Just chose Bedroom 3 because it has whole numbers, none of the other rubbish.

The interior surface area of the bedroom can be calculated by the formula:

2lw + 2wh + 2lh

The surface area is 816 feet squared.

Since we are painting the room twice, we can just double this value for the sake of the next step.

The cost per gallon of paint is $33.98.

Each gallon covers 400 ft^2.

The number of gallons required is (816*2)/400, which is 4.08 gallons. If we approximate that we require 4 gallons, then the total cost will be $33.98*4 = $135.92.

Answer 2

should be $410.81 for living room

Explanation:

13 x 15.5 x 12 = area

area x 2 = two coats of paint on area

two coats of paint on area divided by 400

multiply that by 33.98
