The figure above shows the dimensions of a rectangular box that is to be completely wrapped with paper. If a single sheet of paper is to be used without patching, then the dimensions of the paper could be
(A) 17 in by 25 in
(B) 21 in by 24 in
(C) 24 in by 12 in
(D) 24 in by 14 in
(E) 26 in by 14 in
We need to calculate the surface area.
Surface area of the rectangular box= 2( 16 + 160 + 40) = 432
B is the only option which has a surface area greater than the surface area of the box.
