We apply the conversion factor and the formula for the volume of a pyramid provided in the problem.

43560ft2=1acre. Then,

V-Bh

=13[(13.0acres)(43560ft2acre)]×(481ft)

=9.08×107ft3

Or,

V=(9.08×107ft3)(2.83×101m31ft3)

=2.57×106m3

Result:
20,016.8
Solution:
Given information:
Base area, b=13.0 acres
Height, h=481 ft
First, let's convert the base area from acres to square feet:
b=13.0 acres ×43,560 ft2/acre =566,280 ft2
Now, we can substitute the values into the volume formula of the pyramid:
V=13bh
Substituting the values:
V=13×566,280 ft2×481 ft
Next, we need to convert the volume from cubic feet to cubic meters. We know that:
1 ft =0.3048 m
So, 1 ft3=0.30483 m3=0.02832 m3
Now, we can calculate the volume in cubic meters:
V=13×566,280 ft2×481 ft ×0.02832 m3/ft3
V=13×566,280×481×0.02832 m3
Simplifying the expression, we get:
V=20,016.843648 m3
Therefore, the volume of the pyramid is 20,016.843648 cubic meters.

To find the volume of the pyramid, we can use the formula:
V=13bh
Given that the base area is 13.0 acres and the height is 481 ft, we first convert the base area to square feet:
13.0 acres=13.0×43,560 ft2=566,280 ft2
Now we can substitute the values into the volume formula:
V=13×566,280 ft2×481 ft
Multiplying these values gives us:
V=13×272,408,680 ft3
To convert this volume to cubic meters, we use the conversion factor 1 cubic meter = 35.3147 cubic feet:
V=13×272,408,680 ft3×(1 m335.3147 ft3)
Simplifying the expression gives us the volume in cubic meters:
V=13×7,714,800.28 m3
Therefore, the volume of the pyramid is approximately 2,571,600.09 cubic meters.
