All cubes have six faces. Likewise, the cube shown above also has 6 faces.
[tex]\color{plum}\tt \: Answer \: \: part \: \: 2 :[/tex]
Length of side of one face of cube = 3 inches
Area of one face :
= Side × Side
= 3 × 3
= 9 inch²
Therefore, the area of one face of this cube = 9 inch²
[tex]\color{plum}\tt \: Answer \: \: part \: \: 3 :[/tex]
Area of cube = sum of the area of all faces
Then, the area of this cube :
[tex] = 9 + 9 + 9 + 9 + 9 + 9[/tex]
[tex] = 9 \times 6[/tex]
[tex] = 54 \: \: {inches}^{2} [/tex]
Therefore, the area of this cube = 54 inches²
