Volume of a rectangular prism worksheets
Volume is the third dimension arriving, and the figure has to show it or a child will multiply two numbers and stop. These free printable worksheets draw the box in oblique projection with all three edges labeled.

What's on this sheet
The composite sheets are the standard's own next sentence rather than a variation someone invented: the volume of a solid made of two non-overlapping prisms is the sum of their volumes. It is the step that turns a formula into a method, so it sits alongside the plain boxes rather than in a separate place.
Why this sheet works
The two prisms in a composite figure share a depth. That is not a simplification for the drawing's sake — a step that is narrower front-to-back as well as shorter changes two things at once, and the addition is what is being practiced.
How this one works
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
