Question 222419
Start with the volume of a cube side of length s. Then its volume is:
{{{V[1] = s^3}}} Now we substitute the s with 3*s and calculate the new volume.
{{{V[2] = (3s)^3}}}
{{{V[2] = 27s^3}}} Now substitute {{{V[1] = s^3}}}
{{{V[2] = 27V[1]}}} and you can see that the volume has increased 27-fold.
