The error percentage in measuring the volume of the cylindrical box is 6.3 x 10⁻³ %
<h3>
Error percentage in measuring the volume of the cylinder</h3>
The total error percentage in measuring the volume of the cylinder is calculated as follows;
Volume of cylinder = πr²h
Volume of cylinder = π(0.03r)²(0.07h)
Volume of cylinder = (6.3 x 10⁻⁵)πr²h
Error in measuring the volume = 6.3 x 10⁻⁵ x 100% = 6.3 x 10⁻³ %

Answer:
The speed is 401.76m/s
Explanation:
To find the fundamental frequency we use
3rd.harmonic - 2nd.harmonic = 324Hz
And we know that
f=v/2L
So v=f2L
v= 324 x 2 x 0.62= 401.76m/s
