It depends what type of triange it is.
If it is an equilateral triangle, you can draw 3 lines of symmetry
If it is an isosceles triangle, you can draw 1 line of symmetry
If it is a scalene triangle, you cannot draw any lines of symmetry
It has 4 lines of symmetry on each face which makes 24 of them altogether
a cube has 6 parallel lines

It depends on which type of cuboid we are talking about. If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry. If it is a cuboid with length, width and height all different, then it has three planes of symmetry. If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.
it has 5 planes of symmetry

A cuboid has three orthogonal two-fold axes of symmetry through its centre. It also has three planes of mirror symmetry.
