<PRE><B>Question 263610</B>
The original box is x by x
we cut 6 inches off each corner. The new dimensions are (x-12) by (x-12) and the height is 6.
The volume can be expressed as
{{{V = LWH}}}
in our case as
{{{294 = 6(x-12)(x-12)}}}
or
{{{294 = 6(x-12)^2}}}
dividing by 6 we get
{{{49 = (x-12)^2}}}
taking a square root we get
 {{{7 = x-12}}}
add 12 to get
 x = 19 inches
dimensions are 19 x 19</PRE>
