A room measures 38' x 38' x 10' high. What is the volume of the room in cubic feet?

To find the volume of a room, you use the formula for the volume of a rectangular prism, which is length × width × height. In this case, the room's dimensions are given as 38 feet long, 38 feet wide, and 10 feet high.

Calculating the volume:

1. First, multiply the length by the width:

38 feet (length) × 38 feet (width) = 1444 square feet (this gives the area of the floor).

2. Next, multiply the area (1444 square feet) by the height (10 feet):

1444 square feet × 10 feet = 14440 cubic feet.

Thus, the volume of the room is 14440 cubic feet. This corresponds to choice B, confirming that it is indeed the correct answer.
