A solid cube of side 12cm is cut into eight cubes of equal volume. wat will be the side of the new cube also . find the ratio between thier surface areas (surface area of 8new cubes and the original cube)?>

Side (*a*) of cube = 12 cm

Volume of cube = (*a*)^{3} = (12 cm)^{3} = 1728 cm^{3}

Let the side of the smaller cube be *a*_{1}.

Volume of 1 smaller cube

⇒ *a*_{1} = 6 cm

Therefore, the side of the smaller cubes will be 6 cm.

Ratio between surface areas of cubes

Therefore, the ratio between the surface areas of these cubes is 4:1.*Hope this helps!THUMBS UP PLEASE!! :)*
