A solid cylindrical metal is melted and recast into cubes of metal of sides 3cm . The base radius of the initial cylindrical metal is 10.5cm and height is 63cm. How many cubes will be made

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.

no one knows lol

step-by-step explanation:

one set of data has more variation than the other. hope this !
