Hard Wave Question (Really need help plzz!!)?

The Bay of Fundy, Nova Scotia, has the highest tides in the world. Assume that in midocean and at the mouth of the bay, the Moon’s gravity gradient and the Earth’s rotation make the water surface oscillate with an amplitude of a few entimeters and a period of 12 hours and 24 minutes. At the head of the bay, the amplitude is several metres. Argue for or against the proposition that the tide is magnified by standing wave resonance. Assume that the bay has a length of 210 km and a uniform depth of 36.1 m. The speed of long-wavelength water waves is given by [square root gd] , where d is the water’s depth.

Everything in a proof comes down to the detail definitions.
If the formula given uses g=9.8 and d in meters and the value of the result of completing the computations in the formula is measured in kilometers per hour
If all that is correct then there is a number close to an integer for the number of wave lengths across the bay. If the average depth had been 38 instead of 36 then the fit would have been almost perfect.
