The Great Pyramid of Giza, located in Egypt, has a surface area of \(8.30\times10^4\text{ m}^2\) and a volume of \(2.45\times10^4\text{ m}^3\). A vendor is selling geometrically similar replicas of the pyramid. The replica has a volume of \(9.22\times10^{-6}\text{ m}^3\). Estimate the surface area of the replica, giving your answer in \(\text{m}^2\) and in standard form.[4]
