Think of the formula of surface area of a cuboid.A= 2(lb+bh+hl)

Look at the base. How many sides are there?

You can number the edges, faces and vertices to get the exact count.

Try to fold each net one by one.

Find the missing side of cube and then find the area of cuboid.

First find the radius of cylinder and then find the area of cube by using diameter as side of the cube.

Draw the shpes as per details.

Find the curved surface area of the cylinder and then double it to get the outer surface area.

First, find the surface area of the cuboid and then find the height of the cuboid.

Look at the base. How many sides are there?
