Answer:
Volume = 1299.5 ft³
Step-by-step explanation:
Given the following data;
Side length of the base = 18.1 ft
Height = 11.9 ft
To find the volume of pyramid with a square base,
Volume of square-based pyramid = A(h/3)
Where;
A is the area of the square base.
h is the height of the pyramid.
First of all, we would find the area of the square base;
Area of square = L²
A = 18.1²
A = 327.61 ft²
Next, we find the volume of the square-based pyramid;
Volume = 327.61(11.9/3)
Volume = 3898.559/3
Volume = 1299.5 ft³
