# The Volume of a Cube is 729 Cm3. Find Its Surface Area. - Mathematics

Sum

The volume of a cube is 729 cm3. Find its surface area.

#### Solution

Let the edge of the cube be a.

AS,

Volume of the cube = 729 cm

rArr a^3 = 729

rArr a = root(3)(729)

⇒ a = 9 cm

Now,

Surface area of the cube = 6a2

= 6 × 6 × 9

= 486 cm2

so, the surface area of the cube is 486 cm2 .

Is there an error in this question or solution?
