. Oblicz masę wykonanego z glinu sześcianu o wymiarach 10 cm x 10 cm x 10 cm. Gęstość glinu – 2,7 g/cm 3 .
V = 10cm*10cm*10cm = 1000cm3
1cm3 -ma mase- 2,7g
1000cm3 - ma mase - x
____________________
x=2700g=2,7kg
V=(10cm)³=1000cm³
d=2,7g/cm³
m=d·V
m=2,7g/cm³·1000cm³=2700g=2,7kg
Odp.: Masa wynosi 2,7kg.
