Question

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

Answer 1

Answer:

384cm^2.

Step-by-step explanation:

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

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

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

= 64/1

= 64

Surface area of 1 cube =6(side)^2cm^2

Surface area of 1 cube =6(1)^2cm^2

Surface area of 1 cube =6cm^2

Total surface area of all small cubes =64×6cm^2

=384cm^2.
