Answer:
Height- 4.5 ft
Width- 9 ft
Length- 30 ft
Step-by-step explanation:
Since the scale model is 1/10th (or 10%) of the actual building, you can divide each value given by 10. That's the way I think about it, but what I'm really doing is just multiplying it by the scale factor of 10%, which has the decimal value of 0.1.
I hope this helped!
