  • Side of cube = 7 inches

[tex] \\ [/tex]

[tex] \Large \underline{\tt To \: Find} :[/tex]

  • Total surface area = ?

[tex] \\ [/tex]

[tex] \Large \underline{\tt Solution} :[/tex]

As, we have side of cube is 7 inches.

So, to find total surface area, we have a formula :

[tex] \underline{\boxed{\bf{Total \: surface \: area_{(cube)} = 6(side)^{2}}}}[/tex]

[tex] \tt : \implies Total \: surface \: area = 6 (7 \: inches)^{2}[/tex]

[tex] \tt : \implies Total \: surface \: area = 6 \times 49 \: inches^{2}[/tex]

[tex] \tt : \implies Total \: surface \: area = 294 \: inches^{2}[/tex]

[tex] \\ [/tex]

Hence, Total surface area of given cube is 294 inches².
