qus. A chemical is collected in a tray 2.5 m long and 2m wide. Then this chemical is poured into a glass vessel, which is 50cm long and 25cm wide. If thr height of chemical in the tray was 6.5cm, what be the height of chemical in the glass vessel?

First convert it into cm

Length = 2.5m = 25 / 10 × 100 = 250cm

breadth = 2m = 2 × 100 = 200cm

height = 6.5 cm

see now if u want the lateral surface area then the formula is....
2h ( l + b )

and if u want total surface area then the formula is
2 ( lb + bh + hl )

And then by using any formula u can find the area of the tray and then u have to find the area of the glass vessel.....It can be founded by the same formulas but remember one thing either use the lateral surface area or the total surface area in both the things and think first that which formula is suitable for this sum.....

Then u have the area of the tray so remember that the area of the tray and the glass vessel is same......u can find the height of the glass vessel easily by inserting the formula.....

Hope it will help u.....sorry I can't solve it as it's a very long process but I explained u everything....It will definitely help you

hiii!!!

here's ur answer...

first, the chemical is collected in a tray of Length 2.5m and breadth (wide) 2m and the height of the chemical in the tray was 6.5cm.

length of the tray = 2.5m = 2.5 × 100

= 250cm

breadth of the tray = 2m = 2 × 100

= 200cm

height of the chemical in the tray = 6.5cm

volume of the chemical in the tray = l × b × h

= 250 × 200 × 6.5

= 325000cm³

the chemical which was in tray was then poured in a glass vessel, which is 50cm long and 25cm wide.

length of the glass vessel = 50cm

breadth of the glass vessel = 25cm

volume (quantity) of chemical = 325000cm³

therefore l × b × h = 325000cm³

==> 50 × 25 × h = 325000cm³

==> 1250 × h = 325000cm³

==> h = 325000/1250

==> h = 260cm

hence, the height of the chemical present in the glass vessel is 260cm.

hope this helps...!!
