a = 0.8m b = 0.6m h = 0.5m V =
a = 3dm b = 2.8dm h = 5dm V =
a = 20cm b = 18cm h = 6cm S =
a = 3.2dm b = 1.3dm h = 2.1dm S =
a = 67cm b = 33cm h = 40cm V =
a = 21dm b = 10dm h = 25dm S =
a = 6.3m b = 3.2dm h = 1.6m V =
a = 2.7dm b = 2.3dm h = 0.3dm S =
a = 7.5m b = 5m h = 6m S =
a = 100cm b = 75cm h = 15cm S =
a = 3dm b = 2.5dm h = 4.5dm V =
