Question

A 4 cm cube is cut into 1 cm cubes. Calculate the total surface area of all the small
cubes.​

Answer 1

Answer:

Step-by-step explanation:

Vol. of 4cm cube =(4)3cm3 =64cm3

Vol. of 1cm cube =(1)3cm3 =1cm3

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

                                                            =384cm2
