FORMULA:

Volume of pyramid = L × B × H/3

Height of pyramid = 3V/area of base(L × B)

ANSWER:

So, we have to just plug the respective value.

Height of given pyramid = √(22.1² - 14²)

  • √(488.41 - 196)
  • √292.41 = 17.1m

Now, Volume of given pyramid = 28 × 28 × 17.1/3

  • 784 × 17.1/3
  • 4468.8m³
