Part 1: Design Brief

WALT: Use length × width × height to design a closed rectangular-prism container that meets a target volume.

Success criteria: I can use consistent units, show accurate working, label my design and explain my choices.

1. Our target volume is: ____________   Unit: ____________

Design a closed container. Use the same unit for every measurement.

Formula: Volume = length × width × height

Colour code your labels: Length (blue)   Width (red)   Height (green)

For support, read each instruction aloud, use a ruler or calculator, and check each unit. Challenge: compare which design may use less material.

Part 2: Develop Two Designs

Length: ____________   Width: ____________   Height: ____________

Labelled sketch of the rectangular prism:

Calculation: Volume = ______ × ______ × ______ = __________________

Units: ____________   Does it meet the target?   Yes / No

Length: ____________   Width: ____________   Height: ____________

Labelled sketch of the rectangular prism:

Calculation: Volume = ______ × ______ × ______ = __________________

Units: ____________   Does it meet the target?   Yes / No

We chose option: A / B

Part 3: Prototype, Check and Reflect

Length: ____________   Width: ____________   Height: ____________

Prototype volume: ______ × ______ × ______ = __________________ ____________

Does the prototype meet the target volume?   Yes / No
