Note: <em>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.</em>
Answer:
The total surface are will be: 
Step-by-step explanation:
As we know that
- A cube contains
faces of equal area.
So, the total surface area of the cube is equal to
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:

Thus, the total area of the cube is:

Assuming there are total 5 cubes which are stacked, so the total surface are will:

Therefore, the total surface are will be:
Answer:
In 500 rolls he can expect to get this outcome about 27.77...%* 500 = 139 times.
Answer: x=52.6°
Step-by-step explanation:
To find the value of x, we have to use our SOHCAHTOA. We can eliminate sine and cosine because both uses hypotenuse, which is not labelled. Therefore, we use tangent.

To find x, we want to use inverse tangent.
[plug into calculator]

Now, we know that x=52.6°.
Answer:
2 Hours
Step-by-step explanation:
Required man hours to complete the full job = 12 *15
=180 Man hours
Required man hours to complete the 2/5 of the job = 180/5
= 36 Man hours
if 18 peoples are working,
required hours to complete the 2/5 of the job = 36 /18
= 2 hours
