From Wikipedia
In geometry, a triangular prism is a threesided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides.
Equivalently, it is a pentahedron of which two faces are parallel, while the surface normals of the other three are in the same plane (which is not necessarily parallel to the base planes). These three faces are parallelograms. All crosssections parallel to the base faces are the same triangle.
A right triangular prism is semiregular if the base faces are equilateral triangles, and the other three faces are squares.
The dual of a triangular prism is a 3sided bipyramid.
The symmetry group of a right 3sided prism with triangular base is D_{3h} of order 12. The rotation group is D_{3}of order 6.
The symmetry group does not contain inversion.
It can be considered as a truncatedtrigonal hosohedron.
Volume
The volume of any prism is the product of the area of the base and the distance between the two bases. In this case the base is a triangle so we simply need to compute the area of the triangle and multiply this by the length of the prism:
V = \frac{1}{2} bhl where b is the triangle base length, h is the triangle height, and l is the length between the triangles.

Answers:Yes....there are a few versions. But basically, it is l x w x h / 2
Answers:Well, since the base is an isosceles right triangle, this tells you that the sides are 10 cm, 23 cm, and 23 cm. Knowing that, you can find the area of the base, using the formula for area of a triangle (1/2 bh). Then, you multiply the base times the height of the entire triangular prism, which gives you the volume.
Answers:The volume of a prism is: V = [Area of the Base] * [height] The area of the right triangular base is (1/2) b h V = 90 * 7 = 630 cm^3 QED
Answers:It is area of the cross section times the length in actual fact. So in this case it would be area of the triangle times the length given. I am 100% sure that with Edexcel papers they have a formula sheet with the formula for this given. Oh but they don't give every single formula you need to know. Just a few. Good luck!
