A rock is dropped from a sea cliff, and the sound of it striking the ocean is heard 3.3 later. If the speed of sound is 340 , how high is the cliff?

You need to show the units of your numbers. I will assume they are meters and seconds.

Solve this equation for height, H:

3.23 s = time for sound to arrive + time to fall

3.3 = H/340 + sqrt(2H/9.8)
