Answer:

The surface area is 150.

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 :

$\star{\underline{\boxed{\sf{SA_((Cube)) = 6{a}^(2)}}}}$

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

${\longrightarrow{\sf{SA_((Cube)) = 6{a}^(2)}}}$

${\longrightarrow{\sf{SA_((Cube)) = 6{(5)}^(2)}}}$

${\longrightarrow{\sf{SA_((Cube)) = 6{(5 * 5)}}}}$

${\longrightarrow{\sf{SA_((Cube)) = 6{(25)}}}}$

${\longrightarrow{\sf{SA_((Cube)) = 6 * 25}}}$

${\longrightarrow{\sf{SA_((Cube)) = 150}}}$

$\star{\underline{\boxed{\sf{SA_((Cube)) = 150 \: {cm}^(2)}}}}$

Hence, the surface area of cube is 150 cm².

$\rule{300}{2.5}$
