Rotational symmetry, also known as radial symmetry in biology, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation.
The correct answer for the question that is being presented above is this one: "28 in^2."
We have to get the individual area of each surface. A1 = 1*3*2 = 6 A2 = 1*3*2 = 6 A3 = 1*2*2 = 4 A4 = 2*3*2 = 12 Area = A1 + A2 + A3 + A4 Area = 6 + 6 + 4 + 12 Area = 28 in^2
