What is the total volume calculation for a room that is 16' long, 12' wide, and 7' tall?

1. 192 cubic feet

2. 1344 cubic feet

3. 84 square feet

4. 16,128 cubic feet

The correct answer is: 1344 cubic feet

To calculate the total volume of a room, you need to use the formula for volume, which is length multiplied by width multiplied by height. In this case, the room dimensions provided are 16 feet in length, 12 feet in width, and 7 feet in height. The calculation goes as follows: 1. Multiply the length (16 feet) by the width (12 feet): \( 16 \, \text{ft} \times 12 \, \text{ft} = 192 \, \text{square feet} \). 2. Next, take the area obtained from the first step (192 square feet) and multiply it by the height (7 feet): \( 192 \, \text{square feet} \times 7 \, \text{ft} = 1344 \, \text{cubic feet} \). Thus, the total volume of the room is 1344 cubic feet. This makes the correct answer reflect the accurate application of the volume formula for a three-dimensional space. The other choices either represent incorrect calculations or measurements that are not relevant to volume. For example, one choice refers to square feet, which measures area, not volume, and therefore is not
