Volume with Whole Number Edges

Class Legacy Mission

Seal the Time Capsule

You are the lead builder for the school's 50-year time capsule project. Every memory must fit inside rectangular containers, and the principal needs to know exactly how much each one holds before they are buried. Master volume and the capsule gets sealed for the future.

1. Understand the Question

explain

In the Fold Shop you fold a flat net into a closed box. How does folding the net help you understand what the volume V = l × w × h actually measures?

Your job: Answer the question. Use math evidence. Explain how the evidence proves your answer.Responde la pregunta. Usa evidencia matemática. Explica cómo la evidencia demuestra tu respuesta.

2. Plan Your Math Words

Check at least two words you will use.

Volume — How much space is inside a solid shape.Volumen — Cuánto espacio hay dentro de una figura sólida. Rectangular prism — A solid box shape with six flat rectangle sides.Prisma rectangular — Una figura sólida en forma de caja con seis lados rectangulares. Cubic units — The units used to measure space inside, like cubic inches.Unidades cúbicas — Las unidades para medir el espacio interior, como pulgadas cúbicas. Net — A flat shape that folds up into a solid.Plantilla (desarrollo plano) — Una figura plana que se dobla y forma un sólido. Edge — The line where two flat sides of a solid meet.Arista — La línea donde se unen dos lados planos de un sólido.

When the net folds up, the ___ faces enclose a ___ that I can fill with unit cubes.Cuando la red se dobla, las ___ caras encierran un ___ que puedo llenar con cubos unitarios.

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 volume is three-dimensional, so all three edges (length, width, height) are needed; two measurements only describe one flat face.

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