To find the scale factor, we need to compare the lengths of corresponding sides in the original object and the photograph.
In the original object, each side measures 3 centimeters.
In the photograph, each side measures 8 centimeters.
So, the scale factor is the ratio of the lengths of the corresponding sides:
Scale factor = 8 centimeters / 3 centimeters
Simplifying this ratio, we have:
Scale factor = 8/3
The scale factor is not a whole number, so we'll convert it to a mixed number:
8 ÷ 3 = 2 remainder 2
Therefore, the scale factor is 2 and 2/3.
A more simplified version of 2 and 2/3 is 8/3.
So, the scale factor is 8/3.
