EFGH, ABCD, BCGF, EHAD, HGCD and ABFE are the rectangular faces of the rectangular cuboid.
Thus, a rectangular cuboid has 6 rectangular faces.
Thus, a rectangular cuboid has 6 rectangular faces.

**Explanation:**
A cylinder is a three-dimensional shape that consists of two circular bases and a curved surface connecting the bases. Let's break down the different parts of a cylinder to understand the number of faces it has.
1. **Bases:** A cylinder has two circular bases, one at the top and one at the bottom. The bases are flat and have the shape of a circle. Each base is considered a face of the cylinder.
2. **Curved Surface:** The curved surface of a cylinder is not considered a face. It is a single continuous surface that wraps around the cylinder, connecting the two bases. The curved surface does not have any distinct edges or faces.
Therefore, the number of faces of a cylinder is equal to the number of circular bases it has, which is 2.
Hence, the correct answer is option A) 2.

3d shapes are the shapes having 3 dimensions. A cube has length=breadth=height. So the cube is a 3d shape.

Vertical cut means a perpendicular cut. A perpendicular cut will give the same shape as the side face of the brick. So its rectangular.

Kiran Bajaj answered |
In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges. Along with the rectangular cuboids, any paralle lepiped is a cuboid of this type, as is a square frustum (the shape formed by truncation of the apex of a square pyramid).
