hiii!!!
here's ur answer...
given the side of the cube = 4cm
volume of the cube = side³
= 4 × 4 × 4
= 64cm³
ATQ,
4cm cube is cut into 1cm cubes.
volume of the small cube (side = 1cm) = side³
= 1 × 1 × 1
= 1cm³
therefore no. of small cubes can be cut from the larger cube = 64/1
= 64 cubes
64 cubes can be cut from the larger cube.
TSA of a small cube (side = 1cm) = 6 × side²
= 6 × 1²
= 6 × 1
= 6cm²
hence, TSA of all small cubes = 6 × 64
= 384cm²
hope this helps..!!
