can a refrigerator that is 21.5 cubic feet
hold 20 pounds of ice?
Assuming that the ice is in cube form, we can calculate the volume of 20 pounds of ice. Ice has a density of 0.92 grams per cubic centimeter, which is equivalent to 0.92 kg/liter. Therefore, 20 pounds of ice is equivalent to approximately 9.07 kg.
Since the density of ice is close to that of water (1 kg/liter), we can approximate that 9.07 liters of ice will take up roughly 9.07 cubic decimeters (or liters) of space. This is equivalent to 0.32 cubic feet.
Therefore, a 21.5 cubic feet refrigerator can hold 20 pounds of ice easily.
