Question

Side of a cube increased by 10% percentage increrase in volume

Answer 1

Let the each edge of cube be 100 units.

Then its volume is 1003=1000000 cubic units.

If each edge increases by 10% it becomes 110units

and volume becomes 1103=1331000 cubic units

Therefore increase in volume is 1331000−1000000=331000 cubic units

and percentage increase in volume is 3310001000000×100%

= 33110%

= 33.1%
