An easy way to work this out is to first count the square at the bottom. Next you have to count the edges of that square, because each of these edges will be connected to 1 more face. There are four edges, so that means four more faces. Added to the one face for the square gives us 5 faces total.
This technique can be used for working out the faces of all pyramids - triangle based would be 4 faces total, octagon based would be 9 faces total, and so on.

The area of Blaisy-Bas is 13.27 square kilometers.
The area of Auxelles-Bas is 9,410,000.0 square meters.
Base: Depending on the shape of the base, use the formula for a square, a regular polygon, etc. Height: This must be measured (or calculated) perpendicular to the base.
None - each of the faces (including the bas) is a triangle - triangles do not have any parallel lines.
