Question

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

Answer 1

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
