Written instructions

Draw an arrow. The stem should be vertical...

...and both diagonal lines should be at 30 Degree angles

Step 2: Draw an Open Book

Draw two vertical lines from the ends of the diagonal lines

...and connect the tops of the vertical lines by drawing two lines that are parallel to the diagonal lines at the bottom. You now have what resembles an open book.

Step 3: Finish up the Cube

Finally, create two more diagonal lines, each parallel to the diagonal lines you just created

Use dashed lines to show the edges of the cube that are hidden on the back side of the cube

All together now!
