Answer:
Scale Factor: 343; 82320/240
Step-by-step explanation:
Haven't done scale factors in a long time, so I'll try my best.
The scale factor wants the model to real sculpture, so...
Model: [tex]6*5*8 = 240[/tex]
Sculpture: [tex]42*35*56=82320[/tex]
[tex]\frac{82320}{240} =343[/tex]
So, the scale factor for the model to sculpture would be 343. The fraction that creates the scale factor is [tex]\frac{82320}{240}[/tex].
