Water must be displaced to get the buoyancy to hold up the truck. The weight of the water displaced will be same as the weight of the truck.
 
do i use the P=m/v equation and solve for m?
i would use the density of water for P, and the volume of the water displaced for v, right? I think i understand.
would the answer be 960 kg?
