So the equation for the volume of the pyramid is [tex] V=\frac{lwh}{3} [/tex] . Using the info on the pyramid, we can form the equation [tex] V=\frac{12*12*71}{3} [/tex]


Firstly, multiply everything on the numerator to get [tex] V=\frac{10224}{3} [/tex]


Next, just divide by 3, and your answer will be [tex] V=3408 [/tex]



In short, the volume is 3408 un^3, or the first option.

Volume of regular pyramid be 3408 unit³.

The correct answer is (A).

What is volume of Regular pyramid?

The volume of a Regular pyramid, = 1/3* base area * height. The volume is expressed in cubic units.

Given height =72

length of base side =12

Volume of regular pyramid = 1/3 * base area * height

                                              = 1/3* (12*12) *71

                                              = 48*71

                                             = 3408 unit³

Thus, Volume of regular pyramid be 3408 unit³.
