How do you draw a rectangular prism which has a volume of 4 cm?

Yes ;)

No object can have a volume of 4 cm because 4 cm is a measure of length or distance whereas volume is measured in cubic units.

Nevertheless, describing the process of drawing is difficult because it requires explaining the use of perspective so that a 2-dimensional figure looks like a 3-dimensional solid.

Select one point, O, to be the origin. This will be the bottom-left-front vertex of the prism.

Draw a horizontal line, from O, of any length a cm to the point A. This will be the bottom-right-front vertex.

Draw a vertical line, from O, of any length b cm to the point B. This will be the top-left-front vertex.

Draw a line at an angle to the first two in such a way that it appears to recede into the paper. The length of this line, from O to the point C, should be 4/(ab) cm. C will be the bottom-left-rear vertex.

From A draw the line AD parallel and equal to OC.

From A, C and D draw lines AE, CF and DG parallel and equal to OB.

Join BF, BE, CD, EG and FG.

Volume = OA*OB*OC = a*b*4/ab = 4 cubic cm.
