Question

A 4 centimetre wooden cube is cut into 1cm cubes what is the percentage increase in the surface area after such cutting

Answer 1

✔️✔️note that a Cube has 6 faces.



⭕️The surface area of a cube which has a side of 4cm is 6×4²=6×16 cm².



⭕️when the cube is cut into the smaller cubes and the side of 1cm we get 4×4×4=64 cubes and each will have the surface area equal to 6×1²=6 cm².



⭕️so now the total surface are of these 64 cubes will be 6×64 cm².



⭕️6×64 is 4 times more than 6×16 which means we can say that the percentage is 300% increased!!!!!!!
