Rectangular - PS

by karthikpandian19 » Thu Dec 15, 2011 11:46 pm
The rectangular box with dimensions 8in, 2in, 20in 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

Surface Area of box = 2* (16 + 40 + 160) = 432

Only B has a product greater than 432.
