Question

What is the SURFACE AREA of the cube?

Answer 1

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 2

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)}}}}`

• 
  `\pink\star` SA = surface area
• 
  `\pink\star` a = side

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}`
