Answer:
Option d.
Step-by-step explanation:
Consider the below figure attached with this question.
From the given figure it is clear that the measure side of base is 12 units and height is 71 units.
The base of the pyramid is a square. So the area of base is
[tex]B=side\times side=12\times 12=144[/tex]
The volume of a regular pyramid is
[tex]V=\dfrac{1}{3}Bh[/tex]
where, B is area of base and h is height of the pyramid.
Substitute B=144 and h=71 in the above formula.
[tex]V=\dfrac{1}{3}(144)(71)[/tex]
[tex]V=3408[/tex]
The volume of regular pyramid is 3408 cubic units.
Therefore, the correct option is d.
