Mass Properties - VOLUME

The total volume of my model is 100993.85 cubic meters.

The exact % that increase in space are:
X% - 58
Y% - 33

Calculation for X%
100 993.85 x 58 %
= 58 576.433 cubic meters (the increased space)
100 993.85 – 33 327.9705
= 42 417.417 cubic meters (the finished volume)

Calculation for Y%
100 993.85 x 33%
= 33 327.9705 cubic meters (the increased space)
100 993.85 – 33327.9705
= 67 665.8795 cubic meters (the finished volume)
