PLEASE HELP!!!!

You are on the Titanic and want to find something that will float because you didn't
get on one of the few lifeboats. You grab a large pillow. Measuring it, you find it to
be 55 cm wide, 78 cm long, 25 cm thick, and 5.50 kg.
Will the pillow float?


Sagot :

Find volume of pillow

L=78cm

B=55cm

H=25cm

[tex]\\ \bull\tt\longrightarrow V=LBH[/tex]

[tex]\\ \bull\tt\longrightarrow V=25(78)(55)[/tex]

[tex]\\ \bull\tt\longrightarrow V=107250cm^3[/tex]

[tex]\\ \bull\tt\longrightarrow V=10.72m^3[/tex]

Now

Mass=5.5kg

[tex]\\ \bull\tt\longrightarrow Density=\dfrac{Mass}{Volume}[/tex]

[tex]\\ \bull\tt\longrightarrow Density=\dfrac{5.5}{10.72}[/tex]

[tex]\\ \bull\tt\longrightarrow Density=0.5kg/m^3[/tex]

Density of water=1000kg/m^3

As it is less than density of water it will float on water
