First, let's find the volume of the right rectangular prism using the given edge lengths.
Length = 1/2 inch
Width = 1 1/2 inches = 3/2 inches
Height = 3/4 inch
Volume = Length x Width x Height
Volume = (1/2) x (3/2) x (3/4)
Volume = 9/16 cubic inches
Now, let's calculate the volume of the prism by packing it with unit cubes with an edge length of 1/4 inch.
Since the edge length of the prism is 1/4 inch, each side of the prism can be divided into 2 segments of 1/4 inch each. Therefore, the prism can be seen as a 2x6x3 array of unit cubes.
Total number of unit cubes = 2 x 6 x 3 = 36
Volume = Total number of unit cubes x Volume of one unit cube
Volume = 36 x (1/4 x 1/4 x 1/4)
Volume = 36 x 1/64
Volume = 9/16 cubic inches
As shown above, both methods yield the same volume of 9/16 cubic inches. This demonstrates that the product of the edge lengths of the right rectangular prism is equivalent to the volume found by packing the prism with unit cubes.
multiply the edge length of right rectangular prism with length 1/2 width 1 1/2 and 3/4 to show that the product is the same as the volume you found by packing the prism with unit cubes with an edge length of 1/4 inch.
