The key to this is determining the total volume of water displaced by the boat.
First, calculate the volume with the equation:
V is volume, l is length, w is width, and d is depth
Second, rearrange the density equation and solve for the total mass since we know the volume displaced.
Third, solve for the mass of the boat using Newton's Second Law: (Acceleration is 10 m/s2)
Then solve for mass of just the truck:
Total Mass=Mass Truck+Mass Boat
Mass Truck=Total Mass-Mass Boat
Therefore the maximum weight of the truck is 4280kg.
