Sure, I'd be happy to help!
The length of the model is 4.5 inches and the height is 2 inches. If the length of the actual boat is 18 feet, we can use the scale factor to find the actual size of the boat.
The scale factor is the ratio of the model to the actual size, so we can use it to convert the dimensions of the model to the actual size of the boat. In this case, the scale factor is:
18 feet (actual length) / 4.5 inches (model length) = 4.5 inches / 18 feet
This gives us a scale factor of 1/4.5, or 1/4.5 feet per inch.
Now, we can use this scale factor to convert the dimensions of the model to the actual size of the boat. For example, if the width of the model is 2 inches, the actual width of the boat would be:
2 inches x 1/4.5 feet/inch = 2 x 1/4.5 = 0.8 feet
So, the actual width of the boat would be 0.8 feet.
Similarly, we can calculate the actual height of the boat as follows:
2 inches x 1/4.5 feet/inch = 2 x 1/4.5 = 0.8 feet
So, the actual height of the boat would also be 0.8 feet.
Therefore, the actual size of the boat based on the model is:
Length: 0.8 feet x 18 feet = 14.4 feet
Height: 0.8 feet x 2 inches = 1.6 feet
