Given that the surface area of a cube is given by the formula sa = 6s2, what is the value of sa if s = 1/2 cm. a. 1 cm2 b. 3 cm2 c. 1/2 cm2 d. 1 1/2 cm2

So the formula for the SA of the cube is 6s^2. Given this, and given what "s" is, which is 1/2, we can plug the number into the formula shown.
6(1/2)^2, which will equal 1.5 on the calculator.

So your answer will be D, 1 1/2 cm^2. Hope that helps!
