cubic inches
Cube method:
Each column has 2 cubes, and there are 3 columns total. Therefore, there are a total of 6 cubes in one layer. Since the prism is 2 cubes high, there are 2 layers total.
6 cubes x 2 layers = 12 cubes
Volume = 12 cubes
Volume = 12 cubic inches
Formula method:
Volume = length x width x height
Volume = 3 x 2 x 2
Volume = 12 cubic inches
Answer: 12 cubic inches
not it
not 12 pick another one
I apologize for the confusion. Let's try another method to find the volume.
Using the formula method:
Volume = length x width x height
Volume = 3 inches x 2 inches x 2 inches
Volume = 12 cubic inches
Answer: 12 cubic inches
I hope this is the correct answer. Thank you for your patience.
I apologize for the mistake. Let's correct it:
Using the cube method, we can see that the prism is made up of 12 individual cubes, each with a side length of 1 inch.
