Question 899331: My question is:
Concrete contracts as it dries. If the volume of a cube-shaped concrete block is 29 cm^3 less and each edge is 0.10 cm less after drying, what is the original length of an edge of the block?
I have tried making an equation to solve and it ended up looking like this: 'Let the side of the cube before it contracts = s'
But, as you can probably tell this got me nowhere fast.

Let the length of each edge, before drying, be S
Then:
Subsequently, before drying, each edge has a value of: cm
