# Three equal cubes

Answer :

Given,

Let edge length of three equal cubes = a

Then,

Sum of surface area of 3 cubes =

When these cubes are placed in a row adjacently they form a cuboid.

Length of new cuboid formed = a+a+a = 3a

Breadth of cuboid = a

Height of cuboid = a

Total surface area of cuboid =

=

Hence,

=
