Respuesta:
arista = 3.63 cm
arista = 4.49 cm
Explicación paso a paso:
El area de un cubo = suma del area de todos sus lados, es dicir
a x a x 6
A= 6[tex]a^{2}[/tex]
79 = 6[tex]a^{2}[/tex]
[tex]a^{2}[/tex] = 79/6 = 13.16 cm
a = [tex]\sqrt{13.16}[/tex]
a = 3.63 cm
121 = 6[tex]a^{2}[/tex]
[tex]a^{2}[/tex] = 121/6 = 20.16 cm
a = [tex]\sqrt{20.16}[/tex]
a = 4.49 cm
