there are 24 right angles in all faces of a cube
] ===
A cube has 6 faces, each having 4 right angles, for a total of 24 angles.
All angles in a cube are solid right angles.
On any given face, there are 4 right angles. On an entire cube there are 6 faces, so 6 X 4 = 24 right angles on a total cube
A Rubik's Cube is a perfect cube, hence it has all right angles.
No, all angles are right angles
No, just right angles.
yes
If a triangular based pyramid has any right angles it has three. (Think of the corner of a cube). There are many triangular based pyramids that do not have any right angles.

24 -assuming you mean internal right angles at each corner. Three ate each of 8 corners = 24.
