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.
Answer & explanation
Correct answer: option 2
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
