V = 3.1415 x (Dap) 2 x h x f<br />

4<br />

V = 3.1415 x (0.5mt) 2 x 5mt x 0.75 = 0.736 mt 3<br />

4<br />

2. Calculamos el rendimiento de la troza:<br />

1 m 3 ___________________ 220 pt<br />

0.736 m 3 ___________________ X<br />

X = 0.736 m 3 x 220pt = 16<strong>1.</strong>92 pt = 161 pt<br />

1 m 3<br />
