Answer: This model will fit in the classroom.
Step-by-step explanation:
Since we have given that
Scale model of the solar system :
Diameter of the solar system is given by
[tex]1392000=1.392\times 10^6\ km[/tex]
And the astronomical unit is equal to
[tex]AU=1.5\times 10^8\ km[/tex]
So, we can see that
[tex]AU>Diameter[/tex]
Hence, This model will fit in the classroom.
