6. kero has a plastic container in the shape of a cube. the length of a side is 20 cm. she wants to fill it with 3 liters of water. can her container hold this amount of water? explain you answer. (1 liter = 1000cm3).
my answer-
20x20x20=8,000 cm³
8,000 cm^3=8 liters
3x1000= 3,000 cm³
3,000cm^3=3 liters
so the container can hold 8 liters so it wouldn't be a problem to hold 3 liters.
