A family of shrews has been living in your attic for a few years, and they have finally decided to do some renovation work. The attic is a triangular prism with a height of 10m, whose base is an isosceles triangle with sides 5.2 and 4m. The shrews want to build an additional floor 1m above the attic floor.

1.\bold1. Calculate the surface area of their home before and after the construction of this additional floor.

The shrews now want to install decorations on the ceiling of their new floor.
2\bold2. What is the ceiling height?
3.\bold3. These shrews belong to the species Sorex\it Sorex alpinus\it alpinus and measure between 6.2 and 8.7 cm from the head to the base of the tail. How many shrews will need to stand on top of one another (at minimum and maximum) in order to reach the ceiling?
Only living and whole shrews are taken into account, so the result will be approximated to the nearest lower integer.
