Question

calcule o volume em que cujo as arestas medem 2 /3 cm?

Answer 1

calcule o volume em que cujo as arestas medem 2 /3 cm?
VOLUME = aresta x aresta x aresta
V = axaxa
a = 2/3cm

V = (2/3cm)(2/3cm)(2/3cm)

         2      2        2
V = (------)(------)(--------)cm.cm.cm
          3      3       3

         2x2x2
V = -------------------cm³
        3x3x3

          8
V = -------------cm³
         27

V = 8/27cm³
