Question

an an object of a 15 cm squared and height 2 cm has a mass of 50 grams what is its density in SI unit ​

Answer 1

vol. of object = 15× 2 = 30 cm³

density = mass/vol.

= 50/30

=5/3

=1.66 g/cm³

Answer 2

here is your answer mate...

D = mass / vol

then volume of cuboid= L×B×H= 15×15×2 = 450

then.. putting in. formula....

we get... ...

50g = 50/1000 kg = 1/20 = 0.05

then. 0.05/450 = 0.00011111 kg/cm

hope it helps
