A rectangular boat is 14 m wide and 11 m long.?

After a truck pulls onto the ferry, the boat ends up with a depth of 5 cm submerged under the water. If the weight of the ferry is 10,000 N, what is the maximum weight of the truck? (Assume the density of water is 1000 kg/m3.) Do not include the units in your answer or the computer will mark the problem wrong.

Pls help, I've tried so hard to understand but I kept getting the answer wrong

    Volume of water displaced

    V = 14(11)(0.05)

    V = 7.7 m³

    Weight of water displaced

    W = 7.7 m³(1000 kg/m³)(9.8 N/kg)

    W = 75460 N

    Weight of truck will be the difference between weight of water displaced and the weight of the ferry

    Wt = 75460 - 10000

    Wt = 65460 N

    round as appropriate,

    I am extremely surprised to learn of a boat 14 m wide by 11 m long. That goes against all usual assumptions of boat design. Boats of that sort of size might be around 17 m long and 9 m wide, or 15 x 10. Nobody builds boat wider than they are long. Get your teacher to design questions which reflect the real world.
