Answer :
Final answer:
The concrete canoe displaces approximately 49,001.696 cm³ more water than the Kevlar canoe.
Explanation:
To calculate the amount of extra water displaced by the concrete canoe compared to the Kevlar canoe, we need to find the difference in their volumes. Since the weight of the fluid displaced is equal to the weight of the object, we can use the weight of the canoes to determine their volumes.
Let's assume the density of water is 1 g/cm³. To convert the weights of the canoes to grams, we can use the conversion factor 1 lb = 453.592 g.
The weight of the concrete canoe is 147 lb, which is approximately 66692.424 g. The weight of the Kevlar canoe is 39 lb, which is approximately 17690.728 g.
Now, we can calculate the volumes of the canoes using the formula:
Volume = Weight / Density
The volume of the concrete canoe is approximately 66692.424 cm³ and the volume of the Kevlar canoe is approximately 17690.728 cm³.
Therefore, the concrete canoe displaces approximately 66692.424 cm³ of water, while the Kevlar canoe displaces approximately 17690.728 cm³ of water.
The extra water displaced by the concrete canoe compared to the Kevlar canoe is:
Extra Water Displacement = Volume of Concrete Canoe - Volume of Kevlar Canoe
Extra Water Displacement = 66692.424 cm³ - 17690.728 cm³
Extra Water Displacement ≈ 49001.696 cm³
