Suitcase - rod

The boot of a car has the shape of a cuboid with dimensions 1.6 m × 1.2 m × 0.5 m (width × depth × height). Determine the longest thin rod that can be placed flat on the bottom of the boot.

Final Answer:

d =  2.06 m

Step-by-step explanation:

$$\begin{gathered} a=1.6\text{m} \\ b=1.2\text{m} \\ c=0.5\text{m} \\ {d}^2=a^2+b^2+c^2 \\ d=\sqrt{a^2+b^2+c^2}=\sqrt{1.6^2+1.2^2+0.5^2}=2.06\text{m} \end{gathered}$$
