Question

calculate the surface area of cubes whose sides are ( a) 5cm​

Answer 1

Given :

⬤ Side of Cube is 5 cm .

To Find :

⬤ Surface Area of Cube .

Formula Used :

$\bf[\:{Surface \: Area \:of \: Cube = 6{a}^{2}\:]}$

• a = side

Solution :

According to the Formula :-

6a²

6 × 5 × 5

30 × 5

150

Therefore , Surface Area of Cube is 150 cm .
