PHYSICS
26. The length, breath, and thickeness of
block are measured with the help of a
meter
scale.
Glven
1 = (5.12 +0.01) cm,
b= (10.15+0.01)cm
t = (5.28 0.01)cm. the percentage error in volume is
​

Answer 1

Answer:

Given that,

Length of the block l=(5.12+0.01)cm

Breadth of the block b=(10.15+0.01) cm

Thickness of the block t=(5.28+0.01) cm

We know that,

×100=0.48

%ΔV=0.48%

Hence, the percentage error in volume is 0.48.
