Volume of a rectangular prism is still length × width × height — but now the edges can be fractions or decimals. That means you need to multiply three numbers and handle simple fractions and decimals. Warm those feeder skills and the prism volume formula clicks.
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: 5 × 2 × 3 means 5 × 2 = 10, then 10 × 3 = 30.
Level 1 A number with a dot that shows parts smaller than one whole.
Example: 0.5 is a decimal that means one half.
Level 1 A number that shows part of a whole.
Example: 1/2 is a fraction that means one out of two equal parts.
Level 1 One of two equal parts of something.
Example: Half of 6 is 3, because 6 splits into two 3s.
