    Volume of a 31-gon prism

    A king wanted to build a tower to store all the water for him and his whole family and court.

    The base of the tower is in the shape of a regular triacontakaihenagon, with each side measuring one metre on the exterior, and the tower rises vertically to a height of 31 metres, and it has a flat roof. The walls and roof are 30 centimetres thick.

    How many litres of water are required to fill the entire tower?


    Thanks a lot . Anyone who can solve it will earn my never-ending thanks. Need it for Friday morning .

    That would be a 31-gon then?

    Why the deadline? If it's part of an assessment then it's meant to be your own work not the work of others.
