Question

the density of a material of a cube is calculated by measuring its mass and decide what is the maximum percentage error in the density of the error in the measurement of a side and mass at 3% and 4% respectively​

Answer 1

PLEASE GIVE ME A BRANLIAST ANSWER AND FOLLOW ME

Let M,L and ρ be mass, length and density of cube

So,ρ= M/L³

Percentage error in density =( ∆ρ/ρ)100

{(∆M/M)+3(∆L/L)}100=4+3(3)=13%
