Question

If the length of the diagonal of a cube is $4 \sqrt{3}$ cm, then let us calculate the total surface area of the cube

Answer

Diagonal of a cube $= 4 \sqrt{3}$ cm.

As diagonal of a cube $=\sqrt{3}$ × side.

Length of one side of the cube $=\frac{4 \sqrt{3}}{\sqrt{3}}$ =4 cm

$\therefore$ Total surface area of a cube = 6 × (side)²

= 6 × (4)² = 16 × 6 sq cm

= 96 sq cm

∴ 96 sq cm
