Answer

Explanation:

Step1: Find the sum of volumes

$4.27 + 5.54+47.65=57.46$ L

Step2: Divide by number of plants

There are 3 plants. So, $\frac{57.46}{3}\approx19.1533$ L

Step3: Round to correct significant digits

The least number of decimal - places among the original data is 2. So, the answer is 19.15 L

Answer:

19.15 L
