Question 1208102: Reposted Question:
A faucet is leaking 60 drops per minute. Determine amount of water wasted in 30 days.
A drop is approx. 0.05 milliliters.
With answers of 130 and 129.6 liters, converting to gal.: 130 * .0264 = 34.34 = 34 gal.
I located answers of 113 gal. per month and 1356 gal. per year.
Also, a drop is approx. 1/3 and 1/4 ml.
My question: How did they get the 113 and 1356 ?

You can look for the conversion factor for liters to gallons and use it.

Now it's been about two days. Go back to that. My answer gave fewer significant figures. If you wanted to keep all of them, then you would have 129.6 liters in 30 days. As for using gallons, a quick ref to online shows 1 liter is 0.264172 gallons.

Twenty drops, dilute water solutions, is typically taken as 1 milliliter.
The faucet leaking 60 drops per minute is then leaking milliliters per minute. The 60 is two significant figures, and the 20 is at best, two significant figures. With this and the rest of the calculational setup, the answer should have at best just two significant figures, so 130 liters per those 30 days.
