To find the surface area of the rectangular prism, we need to calculate the area of each of the six sides and then add them together. The area of each of the four walls is the product of the length and height, which gives us:
16 feet × 11 feet = 176 square feet (for the two longest walls)
14 feet × 11 feet = 154 square feet (for the two shorter walls)
The area of the ceiling and floor is the product of the length and width, which gives us:
16 feet × 14 feet = 224 square feet (for the ceiling)
16 feet × 14 feet = 224 square feet (for the floor)
To find the total surface area, we add up the areas of all six sides:
176 + 176 + 154 + 154 + 224 + 224 = 1104 square feet
Therefore, we need at least 1104/100 = 11.04 pints of paint to cover the walls of the room. Rounding up to the nearest whole pint, we need 12 pints of paint.
