LS1 first thought about the shape of their company's shelter and what the shelter is going to protect against. By using that understanding of their shelter, they thought about the materials that they would use for the walls, the ground, the windows and doors (if they have any); and the inner wall layers.
Once they decided on the materials they would use, they needed to calculate how much of those materials they would need for their shelter. The measurement could not be in weight. Measurements that were used often for this task were cubic centimeters and cubic meters.
LS1 enjoyed thinking about which materials they would need for the shelter, and measuring how much material they would need by using their understanding of material properties.
