Measuring volume

Measuring volume by counting unit cubes in layers: find how many cubes are in one layer, then multiply by the number of layers.

Make a sheetDownload PDFThe PDF has this sheet, its answer key and a guide for grown-ups.

How to help

Count the cubes in the bottom layer, like 3 rows of 2 = 6. Count the layers going up. Multiply: 6 × 4 layers = 24 cubic units.

Watch for: Counting only the cubes on the front face. Adding the layers instead of multiplying. Missing the row at the back when counting the bottom layer.

At home: Stack sugar cubes or dice into a box shape one layer at a time. Ask how many are in a layer and how many layers, before counting them all.
