Final answer:
To calculate the volume of a rectangular prism, multiply the length, width, and height.
Step-by-step explanation:
To calculate the volume of a rectangular prism, we multiply the length, width, and height. In this case, the length is 1/5 cm, the width is 2/5 cm, and the height is 3/5 cm.
V = (1/5 cm) x (2/5 cm) x (3/5 cm) = 6/125 cm³
Therefore, the volume of the rectangular prism is 6/125 cm³.
