Well, this is an interesting question, but a tough one to answer without the appropriate data. There are a variety of faucets available in the market and many have different drip rates. Similarly, without knowing the actual drip rate (say 1 drip per second vs. 1 drip per minute) and the volume of the drip, it is really difficult to answer the question.
If we make some simplifying assumptions such as that the drip rate is 1 drip/sec and the drip volume is 0.25 ml, then in 35 seconds, there will be 35 drips and the total water volume wasted would be 8.75 ml.
However, depending on the actual values of these parameters, the answer can be different. One easy way would be to collect the dripping water in a measuring container (such as cup) for a given time duration and measure its volume.
Hope this helps.
