If a room measures 16 feet by 12 feet with an 8-foot ceiling, what is the total square footage of the walls?

To calculate the total square footage of the walls in the room, we first need to determine the area of each wall and then sum these areas.

The room has four walls: two walls measuring 16 feet in length and two walls measuring 12 feet in length. All walls have a height of 8 feet.

1. Calculate the area of the two longer walls (16 feet):

• Area of one wall = height × length = 8 feet × 16 feet = 128 square feet.

• Since there are two of these walls, the total area for the longer walls is 128 square feet × 2 = 256 square feet.

2. Calculate the area of the two shorter walls (12 feet):

• Area of one wall = height × length = 8 feet × 12 feet = 96 square feet.

• For the shorter walls, the total area is 96 square feet × 2 = 192 square feet.

3. Now, to find the total wall area, add the areas of the longer and shorter walls together:

• Total wall area = area of longer walls + area of shorter walls = 256 square feet + 192 square feet = 448 square feet.

Thus, the
