About This Practice

Counting cubes reveals a pattern: the number of unit cubes in a box equals length × width × height — that’s the volume formula. Adjust the dimensions, watch the cubes refill layer by layer, and see the formula update. Then switch to “Verify” to count first and calculate second — the two answers always match!

Adjust length, width and height and watch unit cubes refill the box as V = l × w × h updates live. Switch to “Verify”: count first, then check with the formula!

How to Play

  1. Read the box: what are its length, width and height?
  2. Change them with the + and − buttons and watch the cubes refill.
  3. Watch the formula: which number changed, and how did V move?
  4. Switch to “Verify”: count the cubes first, then tap your answer.
  5. Compare with the formula: do counting and calculating agree?
