Answer:

The surface area is 150.

Step-by-step explanation:

To do this you need to find the area of one of the faces.

5*5=25

Then you should know that there are 6 faces.

25*6=150

Answer:

The option c) 150 cm squared is correct answer.

Step-by-step explanation:

Here's the required formula to find the surface area of cube :

[tex]\star{\underline{\boxed{\sf{SA_{(Cube)} = 6{a}^{2}}}}}[/tex]

  • [tex]\pink\star[/tex] SA = surface area
  • [tex]\pink\star[/tex] a = side

Substituting all the given values in the formula to find the surface area of cube :

[tex]{\longrightarrow{\sf{SA_{(Cube)} = 6{a}^{2}}}}[/tex]

[tex]{\longrightarrow{\sf{SA_{(Cube)} = 6{(5)}^{2}}}}[/tex]

[tex]{\longrightarrow{\sf{SA_{(Cube)} = 6{(5 \times 5)}}}}[/tex]

[tex]{\longrightarrow{\sf{SA_{(Cube)} = 6{(25)}}}}[/tex]

[tex]{\longrightarrow{\sf{SA_{(Cube)} = 6 \times 25}}}[/tex]

[tex]{\longrightarrow{\sf{SA_{(Cube)} = 150}}}[/tex]

[tex]\star{\underline{\boxed{\sf{SA_{(Cube)} = 150 \: {cm}^{2}}}}}[/tex]

Hence, the surface area of cube is 150 cm².
