Q17 of 94 Page 228

If each side of a cube is doubled then its volume

Let the side of the cube be a units

Original volume = a3


Now, when each side of the cube is doubled then its volume:


New side = 2a units


New Volume = (2a)3 = 8a3 cubic units


Therefore, the volume of the cube is 8 times than its original volume


Hence, option D is correct
