Question

If a metal slab of size 1 m x 20 cm x 1 cm is
melted to another slab of 1 mm thickness
and 1 m width, then the length of the new
slab thus formed will be:​

Answer 1

Answer:

200

Step-by-step explanation:

Volume of slab = (100 ×20×1 ) cm's

=2000 cm's ..............(1)

Dimensions of other slab melted = 0.1 cm , 100 cm.

let length be ....x....

=) volume = 0.1×100×x

=10 x ................(2)

equating (1),(2) we get

10 x = 2000

=) x = 2000÷10

= 200

then length is 200cm
