A “3D rectangle” is more formally known as a rectangular prism or a cuboid in geometry. It is a three-dimensional solid shape bounded by six faces, all rectangles. The defining properties of a rectangular prism are: It has six faces, each of which is a rectangle. The opposite faces of the prism are identical. It has 12 edges and 8 vertices.

Now that you have gathered all the necessary materials, let’s begin the journey of drawing a 3D rectangle! Begin by drawing a horizontal line at the center of your paper. Use your ruler to ensure the line is straight and neat. This line will serve as the base of our 3D rectangle.

By following the simple steps, you too can easily draw a perfect 3D Shapes. 1. Begin the 3D shapes outline by using four straight lines to enclose a square. all the sides of a square are the same length. This square will become the front face of a cube. 2. From each of the corners of the square, extend a diagonal straight line.
