% change/error in volume/area if length of edge is changed

% change/error in area/perimeter if length of edge is changed

In the experiment to determine Young's modulus of the material of a wire under tension used in the arrangement as shown. The percentage error in the measurement of length is a in the measurement of the radius of the wire is b and in the measurement of the change in length of the wire is c . Percentage error in the measurement of Young's modulus for a given load is

The quality of the material which opposes the changes in shape, volumer or length is called

Find the percentage error in calculating the volume of a cubical box if an error if 1% is made in measuring the length of edges of the cube.

Find the percentage error in calculating the volume of a cubical box if an error of 1% is made in measuring the length of edges of the cube.

If the percentage error in the measurement of length and breadth of a rectangle are 2% and 3% repectively then the percentage error in the determination of the area is 5%

Find the approximate change in volume V of a cube of side 5m caused by increasing its side length by 2%.
