Sketch a net of the prism and and work out the area of each individual piece and then add them together
A right-angled triangular prism!
It depends on the angle of the plane of the cross section. If it is parallel to the cube's face (or equivalently, two adjacent edges) the cross section will be a square congruent to the face. If the plane is parallel to just one edge (and so angled to a face), the cross section will be a rectangle which will have a constant width. Its length will increase, remain at a maximum level and then decrease. If neither, it will be a hexagon-triangle-hexagon-triangle-hexagon (triangles when passing through a vertex).
triangle
Equilateral, Isosceles or Scalene. For the latter two they could be acute or right angled
It can be a square, a trapezium, a quadrilateral or a triangle - depending on the inclination of the plane which defines the cross section.
A right-angled triangular prism!
The Surface area of a triangle = 0.5*base*height The volume of a prism = area of its cross-section*length
They are all circles. The vertical and horizontal have the same radius as the ball while the angled cross section has a smaller radius.

Answer 1A triangle. Answer 2For a triangular prism, the cross section is a triangle.
Assuming the cross-section is an equilateral triangle with sides of 'a' and the length is 'b' the surface area will be 3ab + SQRT(3).a2

Yes it can.
No, you cannot.
