What is the surface area, in square centimeters, of a 8 inch cube? a. 512 b. 320 c. 256 d. 384

OpenStudy (steven513):

the equations for surface area is A= 6*a^2 so substitute the value of a and finish the problem

OpenStudy (steven513):

so do A= 6*8^2 and you will get an answer. 8 is a in the formula.

Nice job explaining it Steven.
