How to Draw a Recatangular Prism
A rectangular prism is a basic three-dimensional shape, essentially that of a closed box. Also known as a "cuboid," It has six rectangular sides and all corners are right angles. Like a shoe box, not all sides must be equal, but each pair of opposite sides are equal. A special kind of rectangular prism is the cube, in which all sides are equal squares. Drawing a three-dimensional rectangular prism on a two-dimensional surface creates a common and recognizable diagram that requires only a few simple steps.

Draw a basic rectangle, which has four sides that all meet at right angles. Draw each side with a ruler to ensure it is straight. Trace the corners on a second piece of paper to get perfect right angles.

2
Draw a duplicate rectangle of the same size and shape as the first, located diagonally down and to the left of the first rectangle.

Draw four straight lines to connect the four corresponding corners of the rectangles. One line should connect the top left corners of the rectangles, another line connects the top right corners, another joins the bottom left corners, and the final line connects the bottom right corners. This completes a wireframe drawing of a rectangular prism.

Erase three line from the middle of the diagram. Notice in the diagram that near the middle, two points exist at which three lines meet. Choose one of these points and erase the three lines that meet there. This will create the visual impression of an opaque rectangular prism rather than a wireframe or transparent diagram.
