How to calculate the area of a figure

Hello. I need to calculate the area of a small cactus. How can I get the area using revopoint mini? I have read manuals and seen tutorials but have had no luck with that information. Thank you

I haven’t seen that value on the Revopoint software. But here’s how to find it using Autodesk Meshmixer (free). Analysis (left hand sidebar) > Stability > Volume
