Question 577071
{{{Volume = length*width*height}}}
Pretend for a moment that you know the volume of a rectangle is 28cm^3 and you know that the height is 4 and the length is 3.

The formula would read: {{{3*width*4 = 28}}}

You then want to multiply 3 and 4 together (using the multiplicative property) to give you 12 so now it looks like:
{{{12*width = 28}}}

To get the width you now have to divide both sides by the coefficient 12:
{{{(12*width)/12 = 28/12}}}

The 12 cancels out on the left side, and you're left with:
{{{width = 28/12}}}

Which equals 2.333

Width = 2.333
