For this case we have that the volume of the figure is composed of the volume of a prism and the volume of a pyramid:
The volume of the prism is given by:
![V = A_ {b} * h](https://tex.z-dn.net/?f=V%20%3D%20A_%20%7Bb%7D%20%2A%20h)
Where:
: It is the area of the base
h: It's the height
Substituting:![V = 6 * 6 * 6\\V = 216 \ units ^ 3](https://tex.z-dn.net/?f=V%20%3D%206%20%2A%206%20%2A%206%5C%5CV%20%3D%20216%20%5C%20units%20%5E%203)
The volume of the pyramid is given by:
![V = \frac {1} {3} * L ^ 2 * h](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%20%7B1%7D%20%7B3%7D%20%2A%20L%20%5E%202%20%2A%20h)
Where:
It is the area of the base
h: It's the height
Substituting:
![V = \frac {1} {3} * 6 ^ 2 * 5\\V = \frac {1} {3} * 36 * 5\\V = 60units ^ 3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%20%7B1%7D%20%7B3%7D%20%2A%206%20%5E%202%20%2A%205%5C%5CV%20%3D%20%5Cfrac%20%7B1%7D%20%7B3%7D%20%2A%2036%20%2A%205%5C%5CV%20%3D%2060units%20%5E%203)
We add and we have:
![V = 276 \ units ^ 3](https://tex.z-dn.net/?f=V%20%3D%20276%20%5C%20units%20%5E%203)
ANswer:
Option D
An expression to represent a decimal between 1 and 10 multiplied by ten. basically to write larger numbers with less digits.
ex . 100 = 1 x 10^2
ex. 4321= 4.321 x 10^3
R=21. 21/3=7. To check your answer, you can do 7x3 and it'll equal 21.
<span>3. Two isosceles right triangles
Every square has 4 right angles, so each triangle will have one right triangle, which makes the triangles, right triangles.
They are isosceles because all sides of the square are the same, though the diagonal is not.
Hope this helps :)
