Answer 2

Answer:

the are of most of three dimensional figure is found by two ways either total surface area(for cube: area of all sides or faces) or lateral surface area(area of 4 sides or faces), so we are doing both

Total surface area= 6a² (where a is length of side)

=6(8)²

=6×64

=384cm²

lateral surface area =4a²

=4(8)²

=4×64

=256
