Question

pls help me answer this question

Answer 1

Answer:

The cross section is a square of decreasing size

Volume of pyramid = 1/3× area of cross section ×height

Volume of pyramid = 1/3 × area of square × height

Let the height be H

As we know that area of square = S×S

Using this

Volume of pyramid = 1/3×S×S×H

Volume of pyramid = 1/3 × 230 ×230×147

Hence,

Volume of pyramid = 2592100 cm³
