Suppose you have a sample that has a known density of 2.1 g/mL. If you have a mass of 0.34 kg of this substance, what is the volume in units of liters? Note: In your answer, do not include units. Type the numerical answer only or your answer will be counted as being incorrect.

a field is 295 meters long and 38 meters wide. what is its area in square feet (assume that 1 meter is 3.281 ft)

The water depth in a harbour is 17.8 m at high tide and 10.2 m at low tide. One cycle takes 12.4 hours tocomplete. Determine a function, ?(?), that models the depth ? (in meters) of the water at time ? (in hours)with ? = 0 corresponding to low tide

I would like to know how to find it in detail.
