A concrete molding to support a highway bridge is formed by six cylinders 2.1 m in diameter and 10.5 m high surmounted by a prismatic crosspiece whose dimensions are 31.5 m in length by 3.15 m in width and 2.1 m in height.

To paint this structure in white, how many square meters will we have to paint?

Use the approximation π ≈ 3.1416 or the value of the calculator and round your answer to the nearest tenth.
