Anonymous users2024-02-12Solution: 38 cubic decimeters = cubic meters.
Suppose the collected flood samples contain x cubic meters of sediment and the water content is (1000 cubic meters (
x = 2400 x kg.
Divide by kilograms of cubic meters Answer: omitted.

The cluster contains hungry sand + water = total volume of water sample 40dm3
After unifying the units by yourself, the old core can be calculated as x%. Reflux.
