Question 1

You want to build a prototype using blocks. You use sugar cubes because you don’t want to spend a lot of money but they are not durable so they keep breaking.

Using the design matrix, determine which type of block you should use if you don’t want to spend a lot of money but need something very durable.

Answer 1

You should use number cubes because it is the only block that has the highest durable rating while also having a high rating for low cost.
