Question 1111021
{{{V=A*L}}}
{{{V=x^2*L}}}
{{{x^2=V/L}}}
{{{x=sqrt(V/L)}}}
{{{x=sqrt(48.40/250)}}}
{{{x=0.44}}}{{{cm}}}
This value does not match the 4.4 cm value you provided. 
Verify the values for length and volume, also check the units (cm, mm, m) for any discrepancies.

{{{m=rho*V}}}
{{{m=(8.8/1)*48.40}}}
Work that out for the mass in grams.

Assuming 4.4 is correct, there are {{{88/4.4=20}}} bars long the 88 cm measurement. 
Since there are 120 total bars, find the number of bars long on the h side,
{{{N=120/20}}}
{{{N=6}}}
Six bars along that side so the measurement on that side would be,
{{{h=6(4.4)}}}
{{{h=26.4}}}{{{cm}}}
