Volume of a box with rocks

[ukagie]

Could you please tell me the most logical way to go about finding out the volume of a basin when the basin has multiple rocks in it. The rocks take up ~20% of the basin.

Thank You

Do you know the volume of the rocks? Are you needing the volume of the basin with the rocks (how much volume is left over for water), or without (how much volume exists after removing the rocks)? What are the rules for interacting with this object? (Pouring water in until the thing is full, and then pouring back out and measuring, is obvious, so I'm assuming that's against the rules.) How does the exercise define "most logical"?

Please reply with the exact wording of the exercise, as it appears in the assignment, along with a clear listing of everthing you have tried so far. Thank you!

Eliz.

I do not know the volume of the rocks. I am needing the volume of the basin with the rocks. The rocks cannot be removed. Water is already in the basin, with the rocks settled at the bottom. The rocks are not small rocks, rather large chunks of concrete. I do not know how the exercise defines "most logical".

Thank You

I was just going to find the volume of the basin and subtract about 20% of the volume. I did not know if there was another way around it.

Pour measured amount of water into it - till the basin is full.

The volume of water (which you know because you measured) is ~80% of the volume of the basin.

From above calculate the volume of the basin.
