Note: As you have not added the drawing. So, I assume the total number of two-inch cubes are stacked are FIVE. So, I will explain based on that assumption which anyways will clear your concept.
Answer:
The total surface are will be: [tex]\boxed{120\:\:sq.in}[/tex]
Step-by-step explanation:
As we know that
- A cube contains [tex]6[/tex] faces of equal area.
So, the total surface area of the cube is equal to [tex]6[/tex] multiplied by the area of one of the faces.
As the edge of the cube = 2 inches
So, the area of one of the faces is:
[tex]2\times 2=4\:\:sq.in[/tex]
Thus, the total area of the cube is:
[tex]6\times \:4=24\:\:sq.in[/tex]
Assuming there are total 5 cubes which are stacked, so the total surface are will:
[tex]24\times 5=120\:\:sq.in[/tex]
Therefore, the total surface are will be: [tex]\boxed{120\:\:sq.in}[/tex]
