Question

A cube of side 1 cm is broken into smaller cubes of side 4 nm. What is the gain in surface area after the large cube is broken down into smaller pieces?​

Answer 1

Answer:

Vol. of 4cm cube =(4)3cm3 =64cm3

Vol. of 1cm cube =(1)3cm3 =1cm3

Total no. of 1cm cubes =Vol. of 1 cm cubeVol.of 4 cm cube

                                    

                                      =164

                                    

                                      =64

Surface area of 1 cube =6(side)2cm2

Surface area of 1 cube =6(1)2cm2

Surface area of 1 cube =6cm2 

Total surface area of all small cubes =64×6cm2
