Question Statement:

A soybean grain has principal dimensions: major axis $a = 8.0\text{ mm}$, intermediate axis $b = 6.0\text{ mm}$, and minor axis $c = 4.0\text{ mm}$. The geometric mean diameter $D_g = (a b c)^{1/3} = (8 \times 6 \times 4)^{1/3} = 192^{1/3}$ in mm is (rounded off to two decimal places):

Answer Key:

5.77

Step-by-Step Solution & Explanation

$D_g = (192)^{1/3} \approx 5.76899\text{ mm} \approx 5.77\text{ mm}$.
