Question

Mass of solid block is 0.4kg, whose length is 5cm, breadth is 10cm and height is 320mm. Calculate it's density

Answer 1

Answer:

in g/cm cube=0.25 g/cm cube and in kg/m cube=250 kg/m cube

Explanation:

in g/cm cube

density=mass/volume

V=5 cm*10 cm*32 cm (1 mm=1/10 cm 320 mm=320/10cm=32 cm)

v=1600cm cube

mass=400g(1 kg=1000g  0.4kg= 0.4*1000g=400g)

d=mass/volume

400g/1600 cm cube

ans = 0.25g/cm cube

in kg/m cube

1 g/cm cube=1000kg/m cube

0.25 g/cm cube=0.25* 1000kg/m cube=250 kg/m cube

ans=250kg/m cube
