Answer:
surface area of each face of the cube= [tex]15.2 cm^2[/tex]
Step-by-step explanation:
A cube is a three dimensional figure that has all its sides equal.
A cube has six faces:
Area of a cube= [tex]6a^2[/tex]
Area of one face of the cube=[tex]a^2[/tex]
Area of six faces of the cube= [tex]91.2cm^2[/tex]
[tex]6a^2=91.2[/tex]
Dividing by '6' both sides;
[tex]a^2=91.2/6[/tex]
[tex]a^2=15.2cm^2[/tex]
surface area of each face of the cube= [tex]15.2 cm^2[/tex]
