Calculate the total cubic feet of a room that is 10 ft long, 8 ft wide, and 9 ft high.

To find the total cubic feet of a room, you need to multiply the length, width, and height of the room together.

In this case:

• The length of the room is 10 feet.

• The width of the room is 8 feet.

• The height of the room is 9 feet.

The calculation is:

10 feet (length) × 8 feet (width) × 9 feet (height) = 720 cubic feet.

Thus, the total volume of the room is 720 cubic feet. This demonstrates a proper application of the formula for volume calculation, ensuring all dimensions are in the same unit (feet in this case), which is essential for obtaining an accurate measure in cubic feet.

The inclusion of "720 square feet" as one of the options is a common pitfall; volume should always be measured in cubic units, not square units. Therefore, while 720 is mentioned, it is crucial to ensure it is specified as cubic feet when dealing with volume.
