Jayce wants to paint her room Duke Blue.Her room is 12 ft long ,12 ft 10inches wide, and 10ft high.If Dylan insists she paint her ceiling white, about how many cans of blue paint will she need to buy to paint the walls.One can covers 120 square feet. Ignore the windows and doors in the estimate.

2(12 * 10) = 240 square feet

2(12.833 * 10) = 256.67 square feet

240 + 256.67 = 496.67 total square feet

496.67/120 = 4.14 = 5 cans

ITS 12 CANS

Marlene -- you're wrong. You found the volume of the room -- not the square footage of the walls.

It's 5 cans by the way

To find out how many cans of blue paint Jayce needs to buy, we first need to calculate the surface area of the walls.

Step 1: Calculate the area of each wall
The room has four walls: two side walls, one front wall, and one back wall.

The side walls:
Since the room is 12 ft long and 10 ft high, each side wall's area is:
12 ft * 10 ft = 120 square feet

The front wall:
The front wall's area is:
12 ft * 12 ft 10 inches = 144 square feet 10 inches

To convert 10 inches to feet, we divide by 12:
10 inches / 12 = 0.83 feet
So the area of the front wall is approximately:
12 ft * (12 ft + 0.83 ft) = 148 square feet

The back wall:
Since it is similar in dimensions to the front wall, the back wall's area is also approximately 148 square feet.

Step 2: Calculate the total area of the walls
To find the total area of the walls, we add up the areas of each wall:
Total area = 2 * (side walls' area) + (front wall's area) + (back wall's area)
Total area = 2 * 120 square feet + 148 square feet + 148 square feet
Total area = 536 square feet

Step 3: Calculate the number of cans of paint needed
Given that one can of paint covers 120 square feet, we can divide the total area by the coverage of one can:
Number of cans needed = Total area / Coverage per can
Number of cans needed = 536 square feet / 120 square feet per can
Number of cans needed = 4.46 cans

Since you cannot buy a fraction of a can, Jayce would need to buy approximately 5 cans of blue paint to paint the walls of her room.

Remember, this calculation does not take into account windows and doors, so it is an estimate and may result in excess paint.
