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.
These are words you'll need to already know to follow this lesson — not the new words the lesson teaches. Review each one, its meaning, and the example so the new lesson makes sense from the start.
Level 1 To add the same number many times to find a total.
Example: 4 × 5 means add 4 five times, which equals 20.
Level 1 How long something is from one end to the other.
Example: A box that is 5 units long has a length of 5.
Level 1 How wide something is from side to side.
Example: A box that is 3 units wide has a width of 3.
Level 1 How tall something is from bottom to top.
Example: A box that is 4 units tall has a height of 4.
