Answer:
D) V= 1/6 bh
Step-by-step explanation:
The expression that provides the volume of the pyramid is as follows;
As mentioned in the question
It is given that the pyramid put inside a prism
Also the pyramid contains the similar base area but the height is half of the prism
so the base area of the pyramid is b
And, the Height of the pyramid = h ÷ 2
Now as we know that
The volume of the pyramid is
V = 1 ÷3 × base ares × height
= 1 ÷ 3 × b × h ÷ 2
V = 1 ÷ 6 bh
So, the volume is 1 ÷6 bh cube unit.
We must solve
![8 - \frac{7}{10}x = 6 - \frac{1}{5}x \\ or \\ 80 - 7x = 60 - 2x \\ now \\ 20 = 5x \: so \: x = 4 \\](https://tex.z-dn.net/?f=8%20-%20%20%5Cfrac%7B7%7D%7B10%7Dx%20%3D%206%20-%20%20%5Cfrac%7B1%7D%7B5%7Dx%20%5C%5C%20or%20%5C%5C%2080%20-%207x%20%3D%2060%20-%202x%20%5C%5C%20now%20%5C%5C%2020%20%3D%205x%20%5C%3A%20so%20%5C%3A%20x%20%3D%204%20%5C%5C%20%20)
