Question

find the volume and surface area of the following cubes. length =80 cm​

Answer 1

Answer :-

• Volume = 512000 cubic cm.
• Surface Area = 38400 sq. cm.

Explanation :-

Here, we are given with a length of a cube = 80 cm.

And, we have to find volume and surface area of the cube.

Firstly, Let's find Volume.

Formula Used :- (side)³

⇒ Volume = (80)³

⇒ Volume = 80 × 80 × 80.

⇒ Volume = 512000 cubic cm.

Now, Let's find Surface Area of cube.

Formula Used :- 6(side)²

⇒ Surface Area = 6(80)²

⇒ Surface Area = 6 × 80 × 80.

⇒ Surface Area = 38400 sq. cm.

Hence,

• Volume of Cube = 512000 cubic cm.
• Surface Area of Cube = 38400 sq. cm.
