can someone please help me :(

Answer 2

a. Find the area of the walls first. You will have two 18x8 squares and two 14x8 walls. This will give you an area of 2(18x8)+2(14x8)=512.
Because you are using two coats of pain, multiply this number by 2, so the total area is 1024. Because you need to buy a full can of paint, you need to round this number up to 1250 to divide evenly. From this number, you can divide by 250 to find that you need 5 gallons of paint.
cost = 5x9.50 =47.5
The cost for the ceiling will be $47.5.

b. Find the area of the floor. The dimensions will be 18x14, so the area is 252ft2.
For the cost, multiply the area by the cost, so 252x5 = 1260

c. Find the area of the ceiling, which will be the same as the floor, 252ft2.
For the cost, multiply the area by the cost, so 252x7.5 = 1890

d. For the total cost, add all of the costs together, so 47.5 + 1260 + 1890 = 3197.5
