Question

1.
Find the length of the side of a cube whose total surface area measures 600 cm?


​

Answer 1

Total surface area of cube=

$6a {}^{2}$

therefore, 600= 6a²

a² = 100

a = 10 cm.

Answer 2

• Length of side of cube is 10 cm.

Step-by-step explanation:

Given:-

• Total surface area of cube is 600 cm².

To find:-

• Length of side of cube.

Solution:-

We know,

Total surface area of cube = 6 a²

Where

• a is edge or we can say Length of side of cube.

Put total surface area in formula:

⇒6 a² = 600

⇒a² = 600/6

⇒a² = 100

⇒a = √100

⇒a = 10

Therefore,

Length of side of cube is 10 cm.
