Step-by-step explanation:
see the attached figure to better understand the problem
we know that
A cube has six square faces
The surface area of a cube is equal to the area of the six squares faces

where

In this problem we have

substitute


Answer:
I believe it is C
Step-by-step explanation:
Sorry if I got it wrong but hopefully you got it right
The volume of any solid whose base is uniform is V = Ah. Since
the base is a sector of a circle, it’s area is defined by the equation A = θ (r^2)/2, where θ is in radians.
90 degrees in radians
is Pi/2. So the A = (PI) (r^2)/4
Therefore, V = [(PI) (r^2)/4]*h
