Question

The volume of a cuboidal toy box is
8000 cm. Its length and breadth are
40 cm and 20 cm respectively.
Tom wants to find the area of
wrapping paper which would cover the
box exactly. Can you help him by
solving the questions below?
The height of the box =
cm
The surface area of the box =
cm?​

Answer 1

Step-by-step explanation:

Volume of cuboid = lbh

4000=40*20*h

4000/800=h

h= 5 cm

Height=5 cm

now, l=40 cm

b=20 cm

h=5 cm

TSA = 2(lb+bh+hl)

=2[(40)(20)+(20)(5)+(5)(40)]

=2[800+100+200]

=2(1100)

=2200 cm^2

Hope it helps!
