To find the volume of a box, you multiply three edge lengths together: length × width × height. That whole skill runs on solid multiplication facts and being able to multiply three numbers in a row. Warm those up and counting cubes feels easy.

1. What is 4 × 5?
2. What is 2 × 3 × 4?
3. A cube that is 1 unit on every side is called a what?
Volume tells how many unit cubes fill a box. You find it by multiplying the three edges: length × width × height. The answer is measured in cubic units.
Your quick check picks one for you, but you can switch any time:
Level 0 Let's multiply three numbers one step at a time.
A. First step: 2 × 3 = ___
2 groups of 3 is 6.
B. Now finish: take your answer (6) × 4 = ___
6 × 4 = 24.
C. So 2 × 3 × 4 = ___
2 × 3 = 6, then 6 × 4 = 24.
Level 1 Multiply all three edges.
A. 3 × 3 × 2 = ___
3 × 3 = 9, then 9 × 2 = 18.
B. A box is 5 long, 2 wide, 3 tall. How many unit cubes fill it? (5 × 2 × 3)
5 × 2 = 10, then 10 × 3 = 30.
C. Volume is measured in which units?
Volume fills space in 3 directions, so we use cubic units.
Level 2 Stretch into full volume problems.
A. Find the volume: 4 × 3 × 5 cubic units.
4 × 3 = 12, then 12 × 5 = 60.
B. A box is 6 long, 2 wide, 4 tall. What is its volume? (cubic units)
6 × 2 = 12, then 12 × 4 = 48.
1. What is 3 × 4 × 2?
3 × 4 = 12, then 12 × 2 = 24.
2. A box holds 5 cubes across, 2 back, and 2 tall. How many unit cubes is that?
5 × 2 × 2 = 20 cubic units.
