Given:

The edge of each cube is a = 3cm.

To find:

The surface area of the object.

Step-by-step explanation:

The number of outer square surfaces is 22.

The formula for the area of the square is,


A=a^2

So, the total surface area of the object will be,


\begin{gathered} A=22a^2 \\ =22(3)^2 \\ =22*9 \\ A=198cm^2 \end{gathered}

Therefore, the surface area of the object is 198 square cm.

Final answer:

The surface area of the object is 198 square cm.
