Step-by-step explanation:

Let

x ----> the average depth of the resulting layers of ash and rock

we know that

To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.

so

Convert to meters

Remember that

so

Convert to mixed number

assuming you mean addition: addition and subtraction are reverse operations.
