Two cubes, each of volume 512 cm³ are joined end to end. Find the surface area of the resulting cuboid.

Given,

Volume of each cube = 512 cm³

Let length of edge of each cube = a cm

So,

=

= a

When these two cubes are joined end to end a cuboid is formed :

Length of cuboid = 8+8 = 16 cm

Breadth = 8 cm

Height = 8 cm

Surface area of resulting cuboid =

=
