1. **Find the volume of the rectangular prism with dimensions 4 cm, 5.1 cm, and 9 cm.** The formula for the volume of a rectangular prism is: $$V = l \times w \times h$$ where $l$ is length, $w$ is width, and $h$ is height. 2. Substitute the given values: $$V = 9 \times 5.1 \times 4$$ 3. Calculate step-by-step: $$9 \times 5.1 = 45.9$$ $$45.9 \times 4 = 183.6$$ 4. So, the volume is: $$V = 183.6 \text{ cm}^3$$ --- Since the user asked multiple problems but per instructions we solve only the first, the answer is for problem 3 only. **Final answer:** The volume of the rectangular prism is $183.6$ cubic centimeters.
