Answer:

72 mm^3

Step-by-step explanation:

To find the volume of the combined object, we can find the volume of each cube and add it together

Volume of the 4 mm cube

V = s^3

V = 4^3 = 64 mm^3

Volume of the 2 mm cube

V = s^3

V = 2^3 = 8 mm^3

Add the volumes together

64+8 = 72 mm^3

Answer:

72 mm^3

Step-by-step explanation:

To find the volume of this irregular figure, first find each of the cubes.

Part I. Finding the bottom cube

Since the volume of a cube is s^3 where s is the side, we can plug 4 in and we get 64 mm^3.

Part II. Finding the top cube

Using the formula for volume of a cube, we get the volume of the upper cube to be 8 mm^3.

Part II. The total volume of the irregular figure

To find the total volume we simply add the two volumes together. In doing so, we get 64+8 = 72 mm^3 as our volume.
