Prostopadłościan o wymiarach 3cmX25cmx1,2m ma gęstość 500kg/m3. Oblicz jego masę.
BŁAGAM O POMOC!!!!!!!!!
1,2m=120cm
V=3*25*120
V=9000cm3
9000cm3=90m3
d=m/V
m=d*V
m=500kg/m3*90m3
m=45000kg
45000kg=45t
Jego masa wynosi 45 ton.
dane:
a= 3cm
b= 25 cm
h = 1,2m= 120 cm
V=a*b*h
V= 3 cm* 25 cm* 120 cm
V= 9000 cm ^{3} = 90 m ^{3}
d=m/V |*V
m = d * V
m = 500 kg/m^{3} * 90m ^{3}
m = 45000 kg = 45 t
