Apentagonal pyramid has a volume of 1536 in3. what is the volume of the pentagonal pyramid if the measures are multiplied by ?

a. 384 in3
b. 128 in3
c. 96 in3
d. 24 in3

the volume of a cube is 512 cm3. what are the sides multiplied by if the original volume of the cube was 8 cm3?

a. 4
b. 1/4
c. 64
d. 1/64
what are the sides of a rectangular prism increased by if the volume increases from 54 mm3 to 3456 mm3?

a. 2
b. 3
c. 4
d. 5

what is the volume of a rectangular prism when the lengths are tripled? l=5 w=4 h=3

a. 1620 ft3
b. 810 ft3
c. 360 ft3
d. 180 ft3

the radius and height of the cylinder are multiplied by 3. what is the volume of the cylinder?
radius =2 height =5

a. 540π in3
b. 360π in3
c. 180π in3
d. 60π in3

The first question is incomplete.

Question 2:

The volume of a cube is 512 cm³

512 cm³ = 8 cm x 8 cm x 8 cm or sides of 8 cm  

8 cm³ = 2 cm x 2 cm x 2 cm or sides of 2 cm  

So each side got multiplied  by:

times.

Option A is the answer.

--------------------------------------------------------------------------------------

Question 3.

The scale factor can be derived by :

k = 4

Hence, the sides of a rectangular prism increased by 4.

Option C is the answer.

------------------------------------------------------------------------------------------

Question 4.

The original volume is given by = cubic feet

So, when the lengths are tripled, the overall volume is:

So, this can be shown as :

cubic feet

Option A is the answer.

--------------------------------------------------------------------------------------------

Question 5.

The given radius and height are 2 units and 5 units respectively.

Also given, the radius and height of the cylinder are multiplied by 3, so new radius ad height becomes: 6 units and 15 units respectively.

Now, volume of cylinder is given as :

V =

So, the answer will be = V =

= 540π cubic units

Option A is the answer.
