What is the volume of a room with dimensions of 10 feet in length, 14 feet in width, and 20 feet in height?

To find the volume of a room, you multiply its length, width, and height together. In this case, the dimensions provided are 10 feet for length, 14 feet for width, and 20 feet for height.

Calculating the volume involves the following steps:

1. Multiply the length by the width:

10 feet * 14 feet = 140 square feet (this represents the area of the floor).

2. Now multiply that area by the height:

140 square feet * 20 feet = 2800 cubic feet.

This result aligns with the correct answer, which indicates that the volume of the room is 2800 cubic feet. This calculation approach is standard for any rectangular prism, making it applicable for determining the volume of different rooms or spaces with similar dimensions.
