To find the surface area of the new box after applying a scale factor, you need to square the scale factor and then multiply it by the original surface area.
Given:
- Original surface area = 112 cm²
- Scale factor = 34
First, square the scale factor: \[ 34^2 = 1156 \]
Now, multiply the original surface area by this square: \[ \text{New surface area} = 112 , \text{cm}^2 \times 1156 = 129792 , \text{cm}^2 \]
So, the surface area of the new box is approximately 129792 cm².
