Making a life-sized cubic metre!

Te Mihi Community is working on measurement tasks in collaborative workshops on Thursdays and Fridays. We are exploring such topics as perimeter, area, and volume.

Mrs Graham set a task to find out just what one metre cubed looks like. We needed metre rulers, lots of newspaper, and tape for this task. It looked easy but it wasn’t and it took ages. It was messy and frustrating as the newspaper bent in the middle. The trick was to roll the newspaper very tightly.

Angus’ group made their cubic metre and attached it to the wall. It stayed there for a little while and we got to see just how big it is. We could fit inside it.

We learned that a cubic metre is 1m x 1m x 1m. This makes 1m³. It is base x height x width to measure volume. Then we figured out the volume of a 2m cube - 2m x 2m x 2m. It is not 6m³! It is 8m³.

You can ask us why.

We enjoyed this task but not the cleaning up part.
