V is volume of the immersed part of the body in the fluid.
h is the height of immersed part and
A is the area.
Solve for Fb (Buoyant Force) first
Fb=ρghA
Then Solve for V (Volume of the immersed objects e.g. sand+rocks)
V1=[Fb/ρg]
Vt=V1+V2
Where Vt= Total Volume = 300 Gallons = 1135.62 Liters
V1=Total Volume of Objects (Sand+Rocks)
V2= Total Volume of Water
V2=Vt-V1
Good Luck

Great if you're floating a barge and want to figure out the volume it displaces. Let us know how the figuring volume of rock works out
To simplify, I'll guess the rock takes 50g of space. There ya go!
