Calculate volume in Gallons results are questionable

I just used the "Calculate Cut/Fill Volume" tool to calculate the volume of a water pit. The pit was designed to hold 1,000,000 gallons.
I'm calculating the volume using a LiDAR data set and the contours generated from that data set.
In the resulting table:
I've checked the projection of the data and the units. Everything is where it should be.
Using the acreage values I get the correct number of cubic feet and then gallons. But those calculated values don't at all match the gallons calculated by GM.
My question is why the GALLONS/Barrels calculations provided by GM are so off when everything else seems to be right?
thanks,
alex

- I get acreage values that are spot on.
- elevation contours that are spot on.
