To find the volume of the right rectangular prism, we use the formula:
Volume = Length x Width x Height
Given dimensions:
Length = 1 1/3 inches = 4/3 inches
Width = 1 inch
Height = 2/3 inch
Volume = (4/3) x 1 x (2/3)
Volume = 8/9 cubic inches
Now, to find how many 1/3 inch cubes would fit inside the prism, we divide the volume of the prism by the volume of a single cube (1/3 inch):
Number of cubes = (8/9) / (1/3)
Number of cubes = (8/9) x (3/1)
Number of cubes = 8
Therefore, 8 cubes of 1/3 inch would fit inside the right rectangular prism.
