Answer 1

 

Aplicando as relações pertinentes

AREA LATERAL = AL
           AL = 6x([1x90)
                                           AL = 540 cm^2

AREA TOTAL = AT
          AT = 2x(área base) + AL
                                                     área base (área pentágono) = Ab
                                                   Ab = 3(L^2√3)/2
                                                              L = lado
                                                   Ab = 3(1^1x√3)/2
                                                   Ab = 2,51 
         AT = 2(2,51) + 540                
                                                         AT = 545,2 cm^2

VOLUME = V
          V = Ab x altura
             = 2,51 x 90
                                                  V = 225,9 cm^3
