Question

calcular el área de superficie de este cubo. incluir las unidades correctas en la respuesta.

Explanation:

Step1: <Find the area of one face>

The area of one face of a cube is \(A = s^2\), where \(s = 9\) m. So \(A=9\times9 = 81\space m^{2}\)

Step2: <Multiply by the number of faces>

A cube has 6 faces. The surface area \(S = 6\times A\). Substitute \(A = 81\space m^{2}\), then \(S=6\times81=486\space m^{2}\)

Answer:

\(486\space m^{2}\)
