Question

find the ratio of total surface area and total surface area of a cube

Answer 1

Correct Question:

Find the ratio of total surface area and curved surface area of a cube.

Answer:

• Ratio between TSA and CSA of cube is 3 : 2.

Step-by-step explanation:

To Find:

• Ratio of TSA of cube and CSA of cube

Let edge of cube be 'a'.

Now, we know that,

⇒ Total surface area of cube = 6a²

And,

⇒ Curved surface area of cube = 4a²

Now, we will find the ratio between TSA & CSA,

⇒ TSA : CSA = 6a² : 4a²

⇒ TSA : CSA = 6 : 4

⇒ TSA : CSA = 3 : 2

Hence, Ratio between TSA and CSA of cube is 3 : 2.

Answer 2

Correct Question:

find the ratio of Total surface area and curved surface area of a cube

Answer: The ratio of TSA and CSA is 3:2

SOLUTION:

We know that,

The total surface area of a cube = 6a²

The curved surface area of a cube = 4a²

Let the side of the cube be 'a'

Then,

==> TSA : CSA = 6a² : 4a²

==> TSA : CSA = 6 : 4

==> TSA : CSA = 3 : 2

Therefore, the ratio of TSA and CSA is 3:2
