Make a sheetDownload PDFThe PDF has this sheet, its answer key and a guide for grown-ups.
Count every cube in the solid exactly once, including the ones hidden at the back and underneath. That count is the volume in cubic units.
Watch for: Counting only the faces you can see and missing hidden cubes. Counting a corner cube twice because it shows on two sides. Giving the answer in square units instead of cubic units.
At home: Build shapes from sugar cubes, dice or blocks and count the cubes. Try making two different shapes with the same volume.
