Question

Length, breadth and thickness of a block is measured using Vernier callipers. The percentage errors in the measurements are 2%, 1% and 3% respectively. Estimate the percentage error in its volume.

Answer 1

delta v/v*100=deltal/l*100+deltab/b*100+deltat/t*100
2percent +1percent +3percent =
6percent (answer)

Answer 2

Answer:

The percentage error in its volume is 6%.

Explanation:

% error in length = 2%

% error in breadth = 1%

% error in thickness = 3%

We know,

Volume = Length × Breadth × Thickness

V = L × B × H (where, H = height/thickness)

Now,

%ΔV/V×100 = (%ΔL/L×100) + (%ΔB/B×100) + (%ΔH/H×100)

Percentage error in Volume = 2% + 1% + 3%

                                                = 6%

So, the answer is 6%.
