Question

Un cubo cuya arista mide tiene como área superficial …

Answer 1

Answer:

$SA=6x^2\ cm^2$

Step-by-step explanation:

The question in English is

A cube whose edge measures x cm has as its surface area

we know that

The surface area of a cube is equal to the area of its six square faces

so

$SA=6b^2$

where

b is the length side of each square face of the cube

we have

$b=x\ cm$

substitute

$SA=6(x)^2$

$SA=6x^2\ cm^2$
