a triangle is called scalene if no two sides are the same length. the number of scalene triangles whose vertices are the vertices of a given cube is
a. 8
b. 18
c. 24
d. 36
e. 40
the answer is 24. first of all i don't understand the qs so apart from explaining the answer it'd be good to also understand the qs

There are six faces on a cube
Take one face
There are four corners that can be used as verices
4 scalene triangles can be drawn inside the face using each corner as a vertice
To prove it for yourself, just sketch a square and make 4 triangles using the corners as vertices of different size sides
[Actually 4 congruent triangles can be drawn as well]
4 x six faces = 24

There are six faces in a cube take two parallel faces its bisecting plane . Take two diagonally opposite points on one face. Join with the vertices on the opposite face one at a time to get 2 scalene triangles. Similarly take the other face diagonal. It will give you two more scalene triangle. i.e 4 scalene triangles per face .
For six faces we shall have 4×6=24 scalene triangles
For six faces we shall have 4×6=24 scalene triangles
