What is the volume of the regular pyramid below?

For this case we have by definition that the volume of the pyramid shown is given by:
[tex]V = \frac {A_ {b} * h} {3}[/tex]
Where:
[tex]A_ {b}:[/tex] Is the area of the base of a square
h: It's the height
According to the data of the figure shown we have:
[tex]A_ {b} = 10 * 10 = 10 ^ 2 = 100 \ units ^ 2\\h = 81 \ units[/tex]
Substituting:
[tex]V = \frac {100 * 81} {3}\\V = \frac {8100} {3}\\V = 2700 \ units ^ 3[/tex]
Answer:
Option D
Answer:
The correct answer is option D. 2700 units²
Step-by-step explanation:
Formula:-
Volume of pyramid = (a²h)/3
Where a - side of base
h - height of pyramid
To find the volume of pyramid
Here base side = 10 units and h = 81 units
Volume = (a²h)/3
= (10² * 81)/3 = 8100/3 = 2700 units²
Therefore the correct answer is option D. 2700 units²
