Question About CSWA Practice Problem 1.5 Volume

Hello 3DEXPERIENCE Edu / SOLIDWORKS Community,

I was working on the CSWA Practice Problem 1.5 and noticed a possible discrepancy in the volume.

On the exercise sheet, the volume is listed as 0.5492 in³, but when I completed the model, I got 0.5496 in³ instead.

Could someone please double-check whether there might be a typo in the exercise sheet, or let me know if I may have missed something?

The practice problems can be accessed here:

Thank you very much for your help.

Best regards,
Mert
