Question

There is a mountain. The mountain is in the shape of a square pyramid. The base of the mountain measures 120 feet by 30 feet. The height of the mountain is 100 feet. What is the volume of the mountain?

Answer 1

`\bf{Volume=(1)/(3)* (Area~of~base)* Height}\\\\V =(1)/(3) * (120* 30)* 100}\\\\V = (1)/(3) * 3600 * 100}\\\\V = 1200 * 100}\\\\\boxed{\bf{V=120,000~feet^3}}`

Answer 2

Volume of a rectangular pyramid=(1/3)Bh
B=base=120 ft * 30 ft=3600 ft²
h=100 ft

Volume=(1/3)(3600 ft²)(100 ft)=120000 ft³

Answer: 120000 ft³
