If an object thant on the surface displaces 10cm鲁 of water, how much does that object weight?

thant??





I presume that object is floating on the surface.





Mass and weight are different things, but let's ignore that.





The weight of the object is equal to the weight of the water it displaces. 10 cm^3 weighs 10 grams, so that's the weight of the object.
