To find the volume of the rectangular prism, we need to multiply the length, width, and height of the prism.
Length = 3 columns x 1/3 inches = 1 inch
Width = 2 cubes deep x 1/3 inches = start fraction 2 over 3 end fraction inches
Height = 2 cubes high x 1/3 inches = start fraction 2 over 3 end fraction inches
Therefore, the volume of the rectangular prism is:
1 inch x start fraction 2 over 3 end fraction inches x start fraction 2 over 3 end fraction inches
= 1 x start fraction 2 over 3 end fraction x start fraction 2 over 3 end fraction
= start fraction 4 over 9 end fraction cubic inches
So, the volume of the prism is start fraction 4 over 9 end fraction cubic inches.
