Answer

$150$ square meters

Work Step by Step

We are given that the formula $S=6x^{2}$ can be used to find the surface area $S$ of a cube with side length $x$. To find the surface area of a cube with side length 5 meters, we can plug in 5 directly into the formula and evaluate. $S=6(5)^{2}=6\times(5\times5)=6\times25=150$ square meters
