Question

the volume of a box is 426 cm cube and its length and breadth are 3 cm and 2cm respectively. what is the surface area of the box

Answer 1

volume of the box =426 cm^3

length =3 cm

breath=2cm

ATQ,

426=l×b×h

426=3×2×h

426=6×h

426/6=h

h=71 cm

So surface area of the box =2(l×b+b×h+h×l)

=2(3×2+2×71+71×3)cm^2

=722 cm^2
