Answer:
808
Step-by-step explanation:
The volume of the initial cylindrical metal must be equal to the total volume of the cubes.
Let the number of cubes made be x. Therefore:
where 
volume of the cylinder
volume of each cube
Each of the cubes have sides of length 3 cm.
The volume of a cube is given as:
where L = length of side of cube
Therefore, the volume of each cube is:
The volume of a cylinder is given as:
where r = radius
h = height of the cylinder
The volume of the cylinder is:
Therefore:
21823.55 = 27 * x
=> x = 21823.55 / 27
x = 808.27
Since the number of cubes can only be a whole number, the number of cubes that will be made is 808.

Let
s be the speed of the ship, and
c be the speed of the current.
We know that distance equals speed multiplied by the time.
With the current
or
This is our first equation.
Now, against the current, we have
or
This is our second equation.
We solve the equations simultaneously, by adding them together
Substitute s=87.5 to the first equation to solve for c.
The speed of the ship is 87.5 km/hr and the speed of the current is 17.5 km/hr.
7.5442 this means that there is two variables in between
