Answer:

a. k = 27

b. k = 216

c. k = 0.216

Step-by-step explanation:

The value of the scale factor can be given by the following formula:

[tex]k = \frac{Final\ Volume}{Initial\ Volume}[/tex]

where,

Initial Volume = 8 cubic units

a.

Final Volume = 216 cubic units

Therefore,

[tex]k = \frac{216\ cubic\ units}{8\ cubic\ units}[/tex]

k = 27

b.

Final Volume = 1 cubic units

Therefore,

[tex]k = \frac{216\ cubic\ units}{1\ cubic\ units}[/tex]

k = 216

c.

Final Volume = 1000 cubic units

Therefore,

[tex]k = \frac{216\ cubic\ units}{1000\ cubic\ units}[/tex]

k = 0.216
