Answer :
The volume of the rectangular prism is calculated by multiplying the length, width, and height after converting all measurements to the same unit (decimeters), resulting in a volume of 4.8 dm³.
To calculate the volume of the rectangular prism, we use the formula for volume, which is length imes width imes height. However, we need to ensure all measurements are in the same units before calculating. Since the volume is requested in cubic decimeters (dm3), we should first convert the height from millimeters to decimeters. There are 100 millimeters in a decimeter, so 120 mm is equal to 1.2 dm.
Now, using the converted measurement, the volume in cubic decimeters is calculated as follows:
- Volume = length times width times height
- Volume = 2.0 dm times 2.0 dm times 1.2 dm
- Volume = 4.8 dm3
