Surface area is:
\(W=width\)
\(L=length\)
\(H=height\)
\(S=2*(L*W+L*H+W*H)\)
replacing the values
\(250=2*(8*W+8*1+W*1)\)
\(250=2*(8*W+8+W)\)
\(250=2*(9*W+8)\)
dived each member by 2
\(125=9W+8\)
\(9W=125-8\)
\(9W=117\)
\(\boxed{\boxed{W=13~unit~of~measure}}\)
The volume of a rectangular prism is
\(V=L*H*W\)
\(V=8*1*13\)
\(\boxed{\boxed{V=104~unit~of~volume}}\)
