Answer:
Step-by-step explanation:
the formula for density is:
where d is density, m is mass, and V is volume.
solving for m in the last equation:
so if we find the volume and multiply it by the density we will get the mass of the object.
The volume of a rectangular prism is given by:
where is length,
is width and
is height:
we substitute to find the volume:
since the density has units of we need the volume also in units of
, so we make the conversion using:
multiplying by 30:
and now we find the mass with the equation:
substituting d and V:
the nearest gram is:
We know that the volume of a Cylinder is 
We also know that Pi is 3.14, radius is 3 and Height is 4ft
So we do: 3.14*3*4
and the answer is 37.68
But rounded to the hundredths its 37.69 ft^3
