Answer:
The volume of the rectangular prism is 3/20 (or 0.15) mm³.
Explanation:
The volume of the rectangular prism can be calculated as follows:
(1)
Where:
l: is the length = 4/5 mm
w: is the width = 1/2 mm
h: is the height = 3/8 mm
By entering the values of l, w, and h into equation (1) we can find the volume:

Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.
