Answer 1

Answer:

265 (approx)

Step-by-step explanation:

area of rectangle = 7 * 3

                          = 21 m^2

area of semicircle = pi/2 * r^2

                             = pi/2 * 3.5 * 3.5

                           = 11 * 0.5 * 3.5

                            = 1.925 m^2

area of cuboid = 2 (10 * 7 + 7 * 3 + 3 *10)

                      = 2 (70 + 21 +30)

                       = 2 (121)

                       = 242 m^2

total inner surface area =  21 + 1.925 + 242

                                     = 264.925 m^2
