Lesson 28: Drawing a Rectangular Cuboid

Instructions: Practice drawing three-dimensional rectangular cuboids. A rectangular cuboid is a three-dimensional form with rectangular sides and a square cross-section.

Materials: Ruler, drawing paper, drawing implements such as pencils, fine-tipped pens or markers, or charcoal.

Keywords: Rectangular cuboid, cross-section, three-dimensional

Step 1: Draw a square as shown below.
Step 2: Draw a square with the same dimensions above and to the right of the first so that it isn't overlapping, as shown below.
Step 3: Connect the top corners as shown below.
Step 4: Connect the bottom corners as shown below to create a transparent rectangular cuboid.
Step 5: Erase the dotted lines as shown below to make your rectangular cuboid look solid. See how there are two square sides and four rectangular sides.
See below a finished solid rectangular cuboid.
Step 6: Practice drawing additional rectangular cuboids until you master the skill.

Step 7: With a fresh piece of paper, draw anything you wish, but incorporate at least one rectangular cuboid into your artwork. Use glue, scissors, colored paper, markers, paint, or anything else you desire to create your artwork.

See below the painting 'Stilleben Kaffee und Cognac' by Swiss artist Albert Anker. Examine the painting and find the rectangular cuboids. What other three-dimensional shapes can you identify?
