Question

if the error involved in the measurement of side and the mass of a cube are3%and4%. what is the maximum error in the density of the material

Answer 1

Answer:

13 %

Explanation:

d= mass / volume

given a = 3 %

it is known that volume of cube is a³ then error in volume= 3 * 3 = 9% (as power of a is 3 so 3 will be multiplied by error of volume which is also 3)

given that error in mass = 4%

now d= m/v

d = 4 + 9 = 13% (remember errors are always added)
