I found the volume by multiplying ___ × ___ × ___, which equals ___ cubic units.Hallé el volumen multiplicando ___ × ___ × ___, que es ___ unidades cúbicas.

3. Build Your Explanation

Model the parts: This model shows the parts of an explanation. It does not answer your writing question.

Claim: Volume measures space in three directions, so you need length, width, and height.

Evidence: Students explain that volume is three-dimensional, so all three edges (length, width, height) are needed; two measurements only give area of one face.

Reasoning: This evidence connects the definition of volume to the mathematical claim.
