I have a question regarding fluids(adsbygoogle = window.adsbygoogle || []).push({});

A small sculpture made of gold (density of gold = 19280 kg/m^3) is believed to have a secret central cavity. The weight of the sculpture in air is 25.76 N. When submerged in water, the weight is 23.86 N. What is the volume of the secret cavity. (Density of water = 1000 kg/m^3)

The answer is supposed to be volume = 5.7x(10^-5). I can't seem to get that answer. I believe my approach to the problem is wrong.

this is my approach but it is wrong

F=mg

25.76 N = m(9.8 m/s^2)

m = 2.6 kg

density = mass/volume

19280 kg/m^3 = 2.6 kg / v

v = 1.3 x 10^-4

i dont know what to do with the next part after... thanks
