Question

If the side of a cube is ‘ a ‘ cm , its total surface area is​

Answer 1

Answer:

When it is cut into 1 cm cube, the volume of each of the cubes = 1cc. Hence, there will be 64 such cubes. The surface area of the smaller cubes = 6 (12) = 6 cm2. Therefore, the surface area of 64 such cubes = 64 * 6 = 384 cm2.

$\large{\purple \leadsto \mathsf{6a^{2}}}$

$\large{\mathcal{\green{eXplanAtiOn:-}}}$

The area of one side of cube is a×a because it is a square.

And, as it has 6 equal squares, the area will be 6× a².
