Answer 2

Given:

Length of the cube=3cm

To find:

The total surface area of the cuboid so formed​

Solution:

The required area is 234 $cm^{2}$.

We are given that 6 cubes are put together to result in a cuboid.

So, the cuboid's length=sum of the lengths of all 6 cubes.

Its height and width =cube's given length.

Cuboid's length=3×6=18cm

Cuboid's height=Cuboid's width=3cm

The required area=2(length×width+width×height+height×length)

Using values,

Required area=2(18×3+3×3+3×18)

=2(54+9+54)

=2(117)

=234 $cm^{2}$

Thus, the required area is 234 $cm^{2}$.
