Answer:
A balance and a graduated cylinder.
Explanation:
<u><em>Density</em></u> is the relationship between mass and volume of a substance, the formula is:
ρ
Where m is the substance mass, and v is the volume.
If a student wants to measure the density of seawater, he or she should use a Balance, to measure the mass of the sample. And then use a Graduated cylinder, is a volumetric instrument that allows to contain liquids and then measures the exact volume of the sample.
Once the student obtains the mass and the volume, he/she has to replace the data in the density formula and so obtain the density of seawater.

find the area under the curve first
![\int\limits^{\sqrt[3]{\pi}}_0 {x sin(x^3)} \, dx =0.61157809233184](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5E%7B%5Csqrt%5B3%5D%7B%5Cpi%7D%7D_0%20%7Bx%20sin%28x%5E3%29%7D%20%5C%2C%20dx%20%3D0.61157809233184)
then solve c∛π=0.61157809233184
c≈0.41757577488026
round if necicary

alright, solve where they itnersect
x²=y=mx
x²=mx
x²-mx=0
x(x-m)=0
set to zero
x=0
x-m=0
x=m
they intersect at x=0 and x=m
which one is on top?
hmm
y=mx will always be on top (I don't know how to prove that but it's on top)
so we do

solve

so

m³=48
m=2∛6
