Final answer:
The volume of a rectangular prism that is 3 meters long, 7.2 meters wide, and 12.2 meters high is 264.96 cubic meters (m³).
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply its length (l), width (w), and height (h) together. The formula is volume = l × w × h. Therefore, for a rectangular prism that is 3 meters long, 7.2 meters wide, and 12.2 meters high, the volume would be calculated as follows:
Volume = 3 m × 7.2 m × 12.2 m
Volume = 264.96 cubic meters (m³)
The unit of volume is the cubic meter (m³), which is suitable for the size of this prism. Remember, units of volume are derived from units of length, and for smaller volumes, liters (L) or cubic centimeters (cm³) might be used, whereas a cubic meter is a larger unit more suitable for bigger objects like a rectangular prism of the given dimensions.
