The surface area of the prism is 16.8 ft²
What is scaling?
Scaling is the increase or decrease in the size of a figure.
The scale = 1.2 feet / 6 cm = 0.2 ft/cm
9 cm = 0.2 ft/cm * 9 cm = 1.8 ft, 10 cm = 0.2 ft/cm * 10 cm = 2 ft, 16 cm = 0.2 ft/cm * 16 cm = 3.2 ft,
Surface area = 2(0.5 * 3.2 * 1.2) + 2(1.8 * 2) + (1.8 * 3.2) = 16.8 ft²
