Bob built a scale model of the bridge that is 2.637m long at the lowest temperature (T=-45 degrees Celsius) using an unknown material. When the temperature reaches the highest value (T=43 degrees Celsius), he measures again the length of the bridge finding that it has expanded L=5.56mm. Calculate the coefficient of linear expansion and find the material Bob used to make his model.

I need help with correcting this problem. I am at a loss on what I'm doing wrong.
In this problem you will consider the effect that thermal expansion due to temperature will have on Archimedes' principle. Take the densities of water and copper at 0ºC to be 1.00 × 103 kg/m3 and 8.90 × 103 kg/m3, respectively. a. Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 0°C. b. Calculate the fraction of a copper block’s weight that is supported by the buoyant force at 95°C. Assume the volume expansion coefficient of copper is βC = 5.10 × 10-5 1/°C.
A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a. If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
A steel beam 12 m sits next to a concrete wall when the temp is 20 degree A gap must be left between the beam and the concrete wall for expansion purposes.

1 Thermal Expansion A steel rod is 3.000 cm in diameter at 25 °C. A brass ring has an inner diameter of 2.992 cm at 25 °C. At what common temperature – i.e., the same temperature for the rod and ring – will the ring just fit onto the rod? The coefficient of linear expansion of steel is 11 x 10-6/°C. The coefficient of linear expansion of brass is 19 x 10-6/°C.
