Question

A
cuboid
of
dimensions a x b C,
with a < b < c, has to
be cut into two equal
parts across one of
its sides. Which side
should be chosen to
get
maximum
increase in surface
area?​

Answer 1

Answer:

ACuboidwithdimensiona,bandc

Then,volumeofcuboid=a×b×c

V=abccuunit→(i)

andsurfaceareaofcuboid=

S=2×ab+2b×c+2c×a

S=2(ab+bc+ca)sq.unit→(ii)

divideequation(ii)by(i)

⇒
