1.	Q29. A solid cube of side 12 cm is cut into eight cubes of equal volume.What will be the side of the new cube? Also, find the ratio betweentheir surface areas.
Answer» Answer: Side of new CUBES = 6 cm. surface area of bigger CUBE: surface area of smaller cube=4:1. Step-by-step explanation: find find the volume of the solid cube then DIVIDED by 8 then cube root the number your get 6 cm. for surface area: 6A²:6a² where a is the side of smaller cube and A is the side of bigger cube.
