Question

This object is made with five identical cubes. each cube edge is 3 centimeters long.

Answer 1

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.
