Question

9. An aquarium is in the form of a cuboid whose external measures are 80 cm x 30 cm x 40 cm. The base, side faces
and back faces are to be covered with a coloured paper. Find the area of the paper needed.​

Answer 1

Answer:13600cm

Step-by-step explanation:

You have to find the surface area, for a cuboid the surface area is equal to 2lh+2wh+2lw

So let's say

L=40

W=30

H=80

Then

2*80*40+2*30*80+2*40*30

=13600cm
