What is the surface area of the solid below? Round to the nearest tenth. Hint: The surface area only includes the faces on the outside of the solid.

146.8 m^2 to nearest tenth.

Step-by-step explanation:

The surface area = area of the middle 4 rectangles + 2 * curved area + 4 * the semi-circles

= 2*4*6 + 2 *3*6  +  2 * π*2*3 + 4 * 1/2* π 2^2

= 84 + 12π + 8π

= 84 + 20π

= 146.83.
