Answer:
Step-by-step explanation:
✔️✔️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!!!!!!!
