Ste1978 Posted January 26, 2011 Share Posted January 26, 2011 I have a bund with the following properties; Physical Properties for Bund Area General Properties: Material: {Default} Density: 1.000 g/cm^3 Mass: 339392.812 lbmass (Relative Error = 0.000000%) Area: 367.752 m^2 (Relative Error = 0.000000%) Volume: 153.946 m^3 (Relative Error = 0.000000%) How come the are is larger than the volume? I'm sure my brain is not working today Quote Link to comment Share on other sites More sharing options...
MSasu Posted January 26, 2011 Share Posted January 26, 2011 Is that area the exterior surface of your model? If yes this result can be easily explained; see an example based on a box of 2 x 3 x 0.5mm: area = 2 * (2*3 + 2*0.5 + 3*0.5) = 17.0mm² volume = 2 * 3 * 0.5 = 3.0mm³ Regards, Mircea Quote Link to comment Share on other sites More sharing options...
JD Mather Posted January 26, 2011 Share Posted January 26, 2011 ??????? Model a cube 1m x 1m x 1m Volume is 1m^3 Area is the area of the 6 faces. Each face is 1m^2 6 faces on cube is 6 x 1m^2 = 6m^2 units are different m^2 is not m^3 , numbers are meaningless without the units try the same experiment with sides 1000mm x 1000mm x 1000mm 4th grade geometry Quote Link to comment Share on other sites More sharing options...
MSasu Posted January 26, 2011 Share Posted January 26, 2011 Even if is a mathematical abuse, try playing with the area and volume of a sphere – will see that the report is switching at one particular value. Regards, Mircea Quote Link to comment Share on other sites More sharing options...
