See below

#SA=96# sq in.

Explanation:

#V=s^3#
#64=s^3#
find the cubic root of each side
#root(3)64=s#
#4=s" "#so the side of the cube is 4 cu in.

The surface area of a cube is #" "SA=nA#
where #SA# is surface area, #n# is the number of faces, and #A# is the area of one face.

Te area of one face (#A#) is #s^2" "# so #A=16#
#n=6#

#SA=6*16=96#
