1) and 2) alone are insuff.

1) and 2) together are insuff b/c we don't know the dimensions.

1 insuff because we can't figure out the volume.Hence we can't find out the rate.
2 althought we know the capacity the tank can be
1 ________1
1_________1
and

1 ____1
1 ____1
1 ____1
1_____1
my pictures a re schematic and not drawn to scale))sorry
suppose that this figures above are of the same capacity!but the rate we'll be different!
1&2 same insuff so the answer is E
Hope it ll be somehow useful

its E) b/c u dont know the height of the tank. u know the volume, which is 216. its primes are 3^3*2^3. the height can be 3,2,8, etc..u need the height to determine the rate at which water is flowing in. when the height is 2 the water flows in very fast, whereas when the height is 8 the water flows in slower.
