Question #f68d0

Answer 1

`7.5` centimeters

Explanation:

Concepts
Volume regarding 3-dimensional quantity of an enclosed structure; for rectangular prisms like the tanks mentioned here, the formula is `lxxwxxh` -- "length times width times height"

Information
Container A is filled to the brim and its content have a volume of `10xx6xx5=10xx30=300` cubic centimeters.
So we also have `300` cubic centimeters of water.

Container B is empty and its contents will have a volume of `4xx10xxh` (`h` being the height of the water after A is emptied into it)

Steps
To find how high the water level will be in Container B when poured from Container A, we need to set their volumes to be equal (the actual volume of B is negligible, we don't need it for this problem).
So:
`10xx6xx5=300=4xx10xxh`
or `300=4xx10xxh=40xxh`
to get `h` divide: `300/40=7.5`

So the height of the water in Container B will be `7.5` centimeters high.
