Question

The Great Pyramid of Cheops is a square-based pyramid, the base has sides of 230m, and the height is 147m.

Answer 1

Hello,
If you mean by "using the same material" that all is scaled then
using Thales:

$\dfrac{280}{230} = \dfrac{h}{147} \\ ==\textgreater\ h= \dfrac{28*147}{23} =178.9565217....(m)$≈179 (m)
