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

TSA of the 4cm cube is

6L^2

6*4^2

6*16

=96cm square

TSA of 1cm cube

6L^2

6*1^2

=6*1

=6

Then we will divide to see how many small cubes we will have

From this big cube

96:6=16 cubes

So TSA of 16 small cubes

=6 * 16

=96 cm square
