Tess builds a sandbox in the shape of a regular hexagon in which all the sides are 40 inches long. She then takes a photo of the sandbox and prints the photo. In the photo the sides of the hexagon are each 4 inches long

If the sides of the hexagon in the photo are 4 inches long, we can calculate the scale factor between the actual sandbox and the photo by dividing the length of the sides of the sandbox by the length of the sides in the photo.

Actual Length of Sides: 40 inches
Length of Sides in Photo: 4 inches

Scale Factor = 40 inches / 4 inches = 10

Therefore, the scale factor between the sandbox and the photo is 10.

This means that every inch in the photo represents 10 inches in real life.
