Question

At 15 degree the height of Eifel tower is 324m. If it is made of iron, what will be the increase in length in cm, at 30 degree C

Answer 1

Temperature in (Celcius)=15 degrees

Height in this temperature=324m

New Temperature =30 degrees

New length=?

Therefore new length is =324×30÷15

=648m

We know ,

To convert metre into centimetre we have multiply the number by 100

As,1 m = 100 cm

648m = 648×100

=64800cm

Hence,the height of Eiffel tower at 30 degrees will be 64800cm.
