Given is that the ratio of height is 1:100. This means that for every unit of height in the photograph, the real object is 100 times as large. So, e.g. if we have an object that measures 20 cm on the photograph, this means the object is 2000 cm in real life.

So if you have a statue that is 5 cm in height on the photograph, this means the real object is 500 cm (= 5 m) in real life.
