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.
