Question

the density of a cube is measured by measuring its mass and length of its sides. if the maximum error of mass and length are 4% and 3% respectively. the maximum error in the measurement of density would be​

Answer 1

Answer:

error in mass=4%

error in length=3%

error in density=?

density=4%+3%

=7%

Answer 2

Density= mass/ volume

For a cube, density= m/ l^3

Therefore, % error in d= % error in m/ % error in volume

%error in d= 4÷(3*3*3)%

=4/27= 0.148%
