Answer:
Scale Factor: 343; 82320/240
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:
![6*5*8 = 240](https://img.qammunity.org/2022/formulas/mathematics/high-school/93rhce8dv3gbw38i70kgbvq4erh6g0ht8n.png)
Sculpture:
![42*35*56=82320](https://img.qammunity.org/2022/formulas/mathematics/high-school/omadd7q20bbc4o4hopb7xukoj4rwj04hk2.png)
![(82320)/(240) =343](https://img.qammunity.org/2022/formulas/mathematics/high-school/mzw3o0bw629nwjcriu1tnx7luv21lhgz6p.png)
So, the scale factor for the model to sculpture would be 343. The fraction that creates the scale factor is
