The area of one face of a 3cm cube is the area of a 3cm square. That's 3 x 3 = 9cm2.
(A)^3/2
A cube is a three-dimensional solid object bounded by six square faces, facets, or sides, with three meeting at each vertex.The cube formula:Volume of Cube = a³Surface Area of Cube = 6a²Diagonal of Cube = Sqrt(3)*a(a = represents a side)Lets say that the number for the given side is 3, this is how the calculation would look:Volume = a³ = 3³ = 27Surface Area = 6 * 4² = 6 * 9 = 54And the Diagonal = Sqrt(3)*a = Sqrt(3) * 3 = 1.73 * 3 = 5.19
