Answer 1

$\huge\underline\bold\red{ANSWER}$

6× 64 = 384 sq cm

and ratio is 4:1

explanation

total surface area of cube is

6xa sq.

also volume remains constant mn

so volumes we get "64" of 1cm cubes are out of 4cm cube

after that we get total surface area of 64 cubes is

=>6×64 = 384 sq cm

also ratio of small cubes to large cube area is

=>64:16 which gives 4:1 as answer.
