Question

If. The% error in the measurement of a slide of the cube is 2% ,then the percentage error in its volume and area are

Answer 1

Answer:

the percentage error of

volume = 6% and area = 4%

Explanation:

Let, side of cube = a

given,

percentage error of a = 2%

We know that,

if C = Aⁿ , then

percentage error of C = n×percentage error of A

Now,

V = a³, then

the percentage error of volume = 3x2% = 6%

again,

A = 6a²

the percentage error of area = 2x2% = 4%.
