112.2 milliliters volume of water will drip into the bucket in 44 minutes.
<h3>What is volume?</h3>
How much space an object or substance takes up. • Measured in cubic meters (m3), liters (L) & milliliters (mL).
Total drop = Drops per minute X time
= 51 drops per minute X 44 minutes
=2244 drop
Volume of water will drip into the bucket in 44 minutes
=Total drop X Volume of each drop
=0.050 milliliters X 2244 drop
=112.2 milliliters
Hence, 112.2 milliliters volume of water will drip into the bucket in 44 minutes.
