Answer:

Step-by-step explanation:
A three dimensional configuration with its face shaped of rectangle is called a Cuboid. So, the prism is in the shape of a cuboid.
The volume of a cuboid = Length *Breadth*Height

The volume of the cuboid shaped prism is 
To find the mean absolute deviation, you have to find the mean first.
1+1+2+2+2+4=12
12 divided by 6 numbers=2 The mean of that is two
Next, you have to find the amount the original numbers are away from the mean.
1= 1 away from 2 2=0 away from 2 4=2 away from 2
You should get: 1,1,0,0,0,2 Next, you have to find the mean of the new set of numbers. 1+1+0+0+0+2=4
4 divided by 6= 2/3
The mean absolute deviation is 2/3
For simplicity, disregard the fractions. Then you have 48 + (- 39), since opposite signs change into a negative sign, you have 48 - 39. What is the answer?
POSITIVE
It is number C.
It is -11,2,7,8,22
Answer: 120 cm².
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a triangle, which is:

Where <em>b</em> is the base and <em>h</em> is the height of the triangle.
2. Then, when you substitute the values given in the problem you obtain:

3. You know that the shape is made of 12 right triangle of equal size, therefore, multiply the area obtained by 12.
4. Then the area of the shape is:
