1. The problem asks to convert 380 cm at a scale of 1:25 back to actual centimeters. 2. The scale 1:25 means 1 unit on the model represents 25 units in real life. 3. To find the actual length, multiply the model length by the scale factor: $$\text{Actual length} = 380 \times 25$$ 4. Calculate the multiplication: $$380 \times 25 = 9500$$ 5. Therefore, the actual length is 9500 cm.
