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

Ah, a cuboid is a special shape with 9 lines of symmetry. Each face of the cuboid has a line of symmetry running through its center, and there are additional lines of symmetry that go through the midpoints of each pair of opposite edges. It's a beautiful thing to observe the symmetry in nature and mathematics.
