The scale factor from drawing to tree is is 500: Convert to the same units and the difference can be found: How wide is the stem in reality? Cancel Embed. This is a conversion, then subtraction.
In Math and Arithmetic.
Therefore, 500 cm is the longest distance. The volume will therefore be five times five times five times greater. These are often smaller depictions of reality. What is the area in m 2 in reality? A scale of 5: The bicycle in the photo is 5 cm high. There are 100 centimetres in one metre.
The scale factor for the area is 4680:
