Question

When an object floats in water, three-fourths of its volume is beneath the surface. What is the density of the object?


333 kg/m3
1000 kg/m3
750 kg/m3
250 kg/m3

Answer 1

X% volume above water=X%smaller density than that of water

Answer 2

so its 250

Answer 3

25% less dense than water is\[d_W(1-0.25)=1000(1-(0.25))=750\]

Answer 4

sry misread, i calculated the opposite i had to do 1000-250 lol sry

Answer 5

haha, no apology necessary
