Answer

Explanation:

Step1: Find sum of volumes

$17.81 + 0.678+2.00=20.488$

Step2: Divide by number of plants

There are 3 plants. So, $\frac{20.488}{3}\approx6.83$ (rounded to two - decimal places for correct significant digits as the least precise value in the data has two decimal places)

Answer:

$6.83$
