Question

2
find the value of the cube whose surface area is 24 cm ^2.​

Answer 1

Answer:

surtace area of cube =6a²

6a²=24

a²=4

a=2

volume of cube=a³

=(2)³

=8

Answer 2

Answer:

• Side of the cube is 2 cm.
• Volume of cube is 8 cm³.

Step-by-step explanation:

Correct Question:

Find the volume of the cube whose surface area is 24 cm².

Given:

We are given that surface area of a cube is 24 cm².

To find:

We need to find the side and the volume of cube.

Formulae applied:

⇒ Surface area of cube = 6×Side²

⇒ Volume = Side³

Solution:

Let us find the side of the cube by applying surface area of cube formula.

→ 6 × Side² = Surface Area of cube

→ 6 × Side² = 24

→ Side² = 24/6

→ Side² = 4

→ Side = √4

→ Side = 2 cm

Hence, the side of the cube is 2 cm.

Now, let us find volume of cube.

→ Volume of Cube = Side³

→ Volume of Cube = 2³

→ Volume of Cube = 8 cm³

Hence, the volume of cube is 8 cm³.
