पर्याय

• 196 cm²

• 1176 cm²

• 784 cm²

• 588 cm²

Answer 1

The volume of a cube is 2744 cm³. Its surface area is 1176 cm².

Explanation:

Let the edge of the cube be a cm.

Then, volume of the cube = a³

Or,

a³  = (2³ × 7³) 

a = 2 × 7 

a = 14 cm

Therefore, surface area of the cube `= 6"a"^2`

= (6 × 14 × 14) cm²

= 1176 cm²
