Question

6. Weight of an empty tin is 1/6 kg. When it is filled with
sand, it weighs 7/12 kg. Find the weight of the sand?​

Answer 1

Step-by-step explanation:

External volume of box=18×10×6=1080cm^3

internal length=18 -(1/2+1/2)

=17

" breadth=10-1

= 9

" height. =6-1

=5

so, internal volume=17×9×5

=765cm^3

volume of only box (weight)

1080-765

=315

a/q

315cm3=15kg

so 1cm3=315/15

= 21g

again

765cm3=100 kg

so. 1cm3=765/100

=7.65g
