I'm no math head, but you may be able to do this backwards / divided by # of cylinders, but that's a quess.
My math =

Enter Bore/Stroke Designation Type
1 = Inches 2 = Millimeters
Enter Cylinder Bore Size
Enter Piston Stroke Length
Enter Head Gasket Bore Diameter
Enter Compressed Head Gasket Thickness
Enter Combustion Chamber Volume In CCs
Enter Piston Dome Volume In CCs Negative For Dished Pistons (Use '-')
Enter Piston Deck Clearance Negative If ABOVE Deck (Use '-') :

Calculated Engine Compression Ratio xxx
Total Displacement Volume xxx cc
