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'
{{{ (s+0.10)^3=s^3+29 cm^3 }}}
But, as you can probably tell this got me nowhere fast.
Thank you for your help!
<pre>
Let the length of each edge, before drying, be S
Then: {{{S^3 - 29 = (S - .1)^3}}}
Subsequently, before drying, each edge has a value of: {{{highlight_green(S = 9.8819)}}} cm
