Use a triple integral to compute the volume of the pyramid with vertices (0,0,0), (22,0,0), (22,22,0), (0,22,0), and (0,0,44). Set up the triple integral that should be used to find the volume of the pyramid as efficiently as possible.

Final answer:

The volume of the pyramid with specified vertices can be found using a triple integral, with limits from 0 to 22 for both x and y, and 0 to a linear function dependent on x for z, which accounts for the tapering of the pyramid.

Step-by-step explanation:

The volume of the pyramid with vertices at (0,0,0), (22,0,0), (22,22,0), (0,22,0), and (0,0,44) can be calculated using a triple integral. We should aim to set it up such that it is aligned with the pyramid's base and height for efficiency. To find the limits of integration for such a pyramid, consider the pyramid's base in the xy-plane, with vertices at (0,0), (22,0), (22,22), and (0,22). The height extends along the z-axis to (0,0,44).

Since we know the pyramid is symmetrical and has a square base, we can use symmetry to our advantage by setting the limits for x and y from 0 to 22. For the z-axis, because the height of the pyramid is linearly related to x and y, we can set the limit for z from 0 to a linear function that starts at z = 44 when x=0 (on the line y=0) and goes to z=0 as x reaches 22.

Thus, the triple integral to find the volume V would be:

\[ V = \int_{0}^{22} \int_{0}^{22} \int_{0}^{44(1 - (x/22))} dz\, dy\, dx \]
