<u>Height of the pyramid:</u>

  • h = \sqrt{22.1^2 - (28/2)^2} = \sqrt{292.41} = 17.1 m

<u>Volume:</u>

  • V = 1/3Bh
  • V = 1/3*28²*17.1 = 4468.8 m³

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
