Volume of a cube = a³
a³ = 64
a = 4 inches
Surface area of a cube = 6a²
Surface area = 6*4²
= 96 square inches

A cube is six-sided with all sides congruent.
Therefore xxx = 64 and x = 4. Then the surface area is 4X4 = 16 x 6 = 96

Length of side = 4 in
Area of face = 16 in ²
Surface Area of cube = 96 in ²

since volume of a cube is s ^3 (s cubed)
s ^3 = 64
s = 4
surface area is area times height
so area = s ^2
and height is s, which is 4
so surface area is also s^3, which is equal to 64 also :)

each side of the cube = 4 .... 4 * 4* 4 = 16 * 4 = 64 cubic inches ...
SA = 6 * area of a side....
SA = 6[ x^2] .... so SA = 6* [ 4^2 ] = 96 sq inches

= 6([3â64 in]^2)
= 6(4 in ^2)
= 6 * 16 in
= 96 sq in
Answer: 96 square inches
