Answer 1

Answer:

1015+14.5=6597.5

Step-by-step explanation:

csa(coboid)=2(l+b)h

                   =2(8+6.5)35

                   =2(14.5)35

                   = 29*35

                   =1015

ar(floor)=l*b

             =8*6.5

              =14.5

total area=1015+14.5

               =6597.5
