Final answer:
The volume of a pyramid with a square base is calculated using the formula V = (1/3) x base area x height. In this case, the volume is 764.3 m^3.
Step-by-step explanation:
The volume of a pyramid with a square base can be calculated using the formula:
V = (1/3) x base area x height
In this case, the side length of the base is 15.3 m and the height of the pyramid is 19.6 m.
First, calculate the area of the base by squaring the side length:
Area = (15.3 m)^2 = 234.09 m^2
Then, plug the values into the volume formula:
V = (1/3) x 234.09 m^2 x 19.6 m = 764.3292 m^3
Rounding to the nearest tenth of a cubic meter, the volume of the pyramid is 764.3 m^3.
