Answer:

10,080cm for the whole thing.

the lateral part of the triangular prism is 1680cm

Step-by-step explanation:

30 x 25 = 750cm

30 x 24 = 720cm

30 x 7 =  +210cm

              1680cm

25 x 24 =    600cm

600 x 7 = +4200cm

                  4800cm

4200cm x 2 = 8400cm (both of the triangles)

  1680cm

+8400cm

10,080cm
