You seem to be asking me to compare surface area to a volume; this doesn't generally make sense.
There are approximately 0.239913 cubic miles in a cubic kilometer.

There are 144 square inches in a square foot and 1.728 cubic inches in a cubic foot. So you have 7,776 square inches and that would give you 7,776 cubic inches. That would be 4.5 cubic feet.
26,000,000 cubic yards = 0.004769 cubic mile (rounded)
48,430 square miles.
If the search area is circular, the measurement would be in square miles, not cubic miles. If this is the case, the search area would cover 785,000 square miles.
You can't convert square anything to cubic anything. If that were possible, then you'd be able to figure out how many gallons of carpet it would take to cover the floor in your room.
Strangely enough, this is the same as asking how many minutes in a gram, or how many dollars in a light year. The thing is that a cubic measurement is different from a square measurement (which in turn is different from a length measurement). You can't turn square feet into cubic feet, they won't go.
About 478,567,990.765 cubic miles

399 cubic miles = 5.87319828 × 1013 cubic feet

1 cubic yard = 27 cubic feet.
