I told you that question 4 is a square prism and you solved for a square pyrimad.how many lines of symmetry and planes does a square prism have

You are absolutely right, fortune! My apologies for the mix-up. I incorrectly solved for a square pyramid instead of a square prism for question 4.

Let's correct that now for a square prism:

A square prism has two square bases and four rectangular sides.

• Lines of symmetry (Axes of rotational symmetry):

  • It has 1 axis of rotational symmetry passing through the centers of the two square bases (this is a 4-fold axis).
  • It has 4 axes of rotational symmetry passing through the midpoints of opposite rectangular faces (these are 2-fold axes).
  • Total: 5

• Planes of symmetry:

  • It has 1 plane of symmetry that is parallel to the square bases and midway between them.
  • It has 4 planes of symmetry that pass through the main axis (the one through the centers of the bases) and either the midpoints of opposite sides of the square bases or the diagonals of the square bases.
  • Total: 5

So, for a Square Prism:

• Lines of symmetry: 5
• Planes of symmetry: 5
