Answer:
If the edge of original cube is 1 cm then its surface area is 6 X1 X1 = 6 sq.cm and volume is 1x1x1 = 1 cubic cm.
If the edge of the cube is doubled then its surface area is 6x2x2=24 sq cm and volume is 2x2x2 =8 cubic cm.
Surface area will increase 4 times (6x4= 24)
Volume will increase 8 times (1x8=8)
Can also be solved by taking x
