Final answer:
The volume of the cooler is 30000 cm³.
Step-by-step explanation:
To calculate the volume of a rectangular box, you need to multiply its length, width, and height. In this case, the length is 50 cm, the width is 20 cm, and the height is 30 cm. So the formula for volume is:
Volume = length x width x height
Plugging in the values, we have:
Volume = 50 cm x 20 cm x 30 cm = 30000 cm³
Therefore, the volume of the cooler is 30000 cm³.
