Question 1137762


We are told that the box is a cube, meaning all sides are equal.
 
{{{128}}} sandbags, each bag fills a {{{cubic}}}{{{ foot}}}=> total of {{{128ft^3 }}}

so, we know that the {{{volume }}}is {{{128ft^3}}}, and we also know the box is a {{{cube}}}
 
=> {{{volume = side * side * side = side^3}}}

 {{{side^3=128ft^3 }}}

{{{side=root(3,128)}}}

{{{side=root(3,64*2)}}}

{{{side=root(3,4^3*2)}}}

{{{side=4root(3,2)}}}=>exact solution

{{{side=5.04ft}}}->approximate solution
