5. What we measured:
The column in front of the school building (photo A):
The length of the shadow casted by the column -2.82m
The length of the shadow casted by the stick-0.94m
The height of the column-2.82: 0.94 =3.00m A

6. B The length of the shadow casted by the stick-0.73 m
The bell tower (photo B):
The length of the shadow casted by the bell tower m
The height of the bell tower-15.20: 0.73 =20.80 m B

7. C The church of Saint.Maria Assunta (photo C):
The length of the shadow casted by the stick-0.76m
The length of the shadow casted by the school building -
the height of the school building 13.16m : 0.76 =17.30m C
