If each side of a cube is doubled, its surface area A. is doubled B.

1.	If each side of a cube is doubled, its surface area A. is doubled B. becomes 4 times C. becomes 6 times D. becomes 8 times
Answer» Let the side of the cube be “a” unit Original Surface area = 6a² sq units Now, when each side of a cube is doubled than its surface area: New surface area = 6 (2a²) sq units = 24a² sq units Therefore, the surface area of the cube is 4 times than its original area Hence, option B is correct

If each side of a cube is doubled, its surface area A. is doubled B. becomes 4 times C. becomes 6 times D. becomes 8 times

Answer»

Let the side of the cube be “a” unit

Original Surface area = 6a² sq units

Now, when each side of a cube is doubled than its surface area:

New surface area = 6 (2a²) sq units

= 24a² sq units

Therefore, the surface area of the cube is 4 times than its original area

Hence, option B is correct
