Find the height of a right pyramid if its base is a square of side 80 cm and the volume of the pyramid is 16000 cm³.

7.5 cm

We know that,

Volume of pyramid = \(\frac{1}{3}\) × area of base × height

The side of the base = 80 cm

Volume = 16000 cm³

According to the question , 16000 = \(\frac{1}{3}\) × 80² × height

16000 = \(\frac{1}{3}\) × 6400× height

48000 = (6400 × height)

 height = 7.5
