The diagonal of a cube is 2√ 3 cm. Find the surface area of the cube.

Given, diagonal = 2√ 3 ⇒ a√ 3 = 2√ 3 [a = edge of the cube] ∴ a = 2 ∴ Required surface area = 6a 2 = 6 x 2 2 = 24 sq cm

Question

Accepted Answer

Given, diagonal = 2√3
⇒ a√3 = 2√3 [a = edge of the cube]
∴ a = 2
∴ Required surface area = 6a²
= 6 x 2² = 24 sq cm
