Question

HEYA FRIENDS!!

Question - :
The volume of a plastic covered sealed box is 350 cm^3 and the box has a mass 500g . Will the box float on water or sink in water ? What will be the mass of water displaced by the box ?

plz answer in simple and in easy understandable method ..Ans fast tomorrow is my exam..

Answer 1

It sinks.

It's density is 10/7 g/cm³

500/350

while Water's is 1 g/cm³

so if 2 similar volumes of both (water and that box)
are used the former will be lighter.

P.S SAVE PENGUINS

P.P.S THO WE CAN LIVE ON ICE, WE CAN'T LIVE ON WATER SO STOP GLOBAL WARMING FOR US.

P.P.P.S ICE FLOATS (THE ONLY SUBSTANCE TO DO SO as in solid floating in liquid)

Answer 2

Given ---
Mass of packet = 500 gm
Volume of packet = 350 cm³

Therefore,
Density of packet = m/v
$= \frac{500}{350}$

$= 1.42$

Density of packet = 1.42 g/cm³

Now, we know that density of water = 1 g/cm³
And, Density of packet = 1.42 g/cm³

Since density of packet is more than density of water, hence packet will sink.

Now, for water,

Volume = 350 cm³
Density = 1 g/cm³

Since, Density = mass / volume

=> mass = Density × volume

$= 350 \times 1$

$= 350$

Hence, 350 g of water will be displaced.

Hope this answer helps you.. :-)
