Answer:
B
Step-by-step explanation:
Given:
Base of the pyramid = 16 inches
Height of the base (h) = 20 inches
Height of the pyramid (H) = 15 inches
To find:
The volume of the triangular pyramid.
Solution:
Area of the base (B) =
Area of the base (B) = 160 in²
<u>Volume of triangular pyramid:</u>
where B is base area and h is the height of the pyramid.
in³
The volume of the triangular pyramid is 800 cubic inches.
Answer:
Step-by-step explanation:
means single part out of 5,
Since,
Similarly, means 2 parts out of 10.
Now we can shade 2 parts out of 10 to show of the given figure.
(As shown in the figure attached)
2x + 3x - 10 = 70
5x - 10 = 70
5x = 70 - 10
5x = 60
x = 60/5
x = 12
Now that we know the value of x,
the value of QSR = 3(12) - 10.
QSR = 36 - 10
QSR = 16
