Final answer:
The rectangular prism with the largest volume has dimensions of l = 5 cm, w = 3 cm, and h = 5 cm.
Step-by-step explanation:
To find the largest volume of a rectangular prism, we need to calculate the volume of each prism and compare the results. The formula for the volume of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height.
Let's calculate the volumes:
Prism 1: V = 4 cm × 5 cm × 3 cm = 60 cm³
Prism 2: V = 6 cm × 3 cm × 3 cm = 54 cm³
Prism 3: V = 2 cm × 6 cm × 6 cm = 72 cm³
Prism 4: V = 5 cm × 3 cm × 5 cm = 75 cm³
Therefore, the prism with the largest volume is Prism 4, with a volume of 75 cm³.
