The domain for f(t) is all of the numbers t for which f(t) is defined.
In other words, its all of the numbers that t minutes can be and still make sense in the function.
f(t) is distance from sea level as a function of time. It does not make sense to have negative time, so t must be 0 or a positive number. t does not necessarily have to be an integer (a whole number), since you can have time values like half a minute.

Let L and H represent length and height, respectively.
.. 20 ft = (4/5)*L
.. L = (5/4)*(20 ft) = 25 ft . . . . . . . . multiply by the reciprocal of the coefficient of L
.. H = (2/9)*(L +20 ft)
.. = (2/9)*(25 ft +20 ft))
.. = (2/9)*(45 ft) = 10 ft
The volume is the product of length, width, and height.
.. V = (25 ft)*(20 ft)*(10 ft) = 5000 ft^3
