Question

find the volume of cube whoes T.S.A is 487cmsq.​

Answer 1

Answer:

• Volume of cube = 729 cm³

Explanation:

Given:

• Total surface area of cube = 487 cm²

To Find:

• Volume of cube

We know that,

⇒ Total surface area of cube = 6a²

⇒ 487 = 6a²

⇒ a² = 487/6

⇒ a² = 81.16

⇒ a = 9 cm (Approx)

Now, we know that

⇒ Volume of cube = a³

⇒ Volume of cube = (9)³

⇒ Volume of cube = 729 cm³

Hence, Volume of cube = 729 cm³.

Extra Info:

• Total surface area of cube = 6a²
• Lateral surface area of cube = 4a²
• Volume of cube = a³

Answer 2

Answer:

729 cm^3

Explanation:

total surface area = 487 cmsq

6a^2 = 487

a^2 = 487/6

a^2 = 81.1

a = √81.1

a= 9.00

volume of cube = a^3

= (9)^3

= 729 cm^3
