Question

If each side of a cube is halved, its surface area will be __________________.
(a) halved (b) one-fourth (c) doubled (d) same

Answer 1

Answer:

b)

Step-by-step explanation:

Surface area of a cube = 6a²   , here a is the side of cube

When side is halved, side = a/2

Now, the surface area of new cube = 6* (a/2)²

                                                           = $6*\frac{a^{2}}{4}=\frac{1}{4}*6a^{2}$

                                                            = one fourth of the cube
