To find the surface area (SA) of a cube given the length of its side (s), we can substitute the value of s into the formula SA = 6s^2.
In this case, s = 1/2 cm.
Substituting s = 1/2 cm into the formula, we get:
SA = 6(1/2)^2
SA = 6(1/4) (Squaring 1/2 gives 1/4)
SA = 6/4
SA = 3/2 (Dividing 6 by 4 gives 3/2)
Therefore, the value of SA is 3/2 cm^2.
The correct option is D) 1 1/2 cm^2.
