Let's start by finding the area of the base triangle. To do this, we can use Heron's formula since we know all three side lengths:
First, calculate the semi-perimeter:
s = (a + b + c) / 2
s = (16 + 14 + 8) / 2
s = 19
Now, calculate the area of the triangle using Heron's formula:
Area = sqrt[s * (s - a) * (s - b) * (s - c)]
Area = sqrt[19 * (19 - 16) * (19 - 14) * (19 - 8)]
Area = sqrt[19 * 3 * 5 * 11]
Area = sqrt[3135]
Area ≈ 56.03 m^2
Since the base triangle of the prism and pyramid have the same area, we can proceed to calculate their volumes:
Volume of the prism = base area * height = 56.03 * 15 = 840.45 m^3
Volume of the pyramid = (1/3) * base area * height = (1/3) * 56.03 * 15 = 280.15 m^3
Therefore, the volume of the prism is 840.45 m^3 and the volume of the pyramid is 280.15 m^3.
