Cual es el volumen del cubo de rubick cuya arista mide 3 cm

Natasha2012 [34]

For this case we are asked the following question:

"What is the volume of the rubick's cube whose edge measures 3 cm"

By definition, the volume of a cube is given by:

$V = l ^ 3$

Where:

l: Is the side or the edge of the cube

According to the statement we have:

$l = 3 \ cm$

Substituting:

$V = 3 ^ 3\\V = 3 * 3 * 3\\V = 27$

Finally, the volume of the cube is $27 \ cm ^ 3$

Answer:

$27 \ cm ^ 3$
