David used the scale 1 centimeter equals 5 meters to build a model boat.

Question

 
If the model boat is 8 centimeters long, how long is the full-size boat?

Answer 1

To find the length of the full-size boat, you can use the scale provided. The scale is 1 centimeter equals 5 meters.

If the model boat is 8 centimeters long, you can calculate the full-size length as follows:

\[ \text{Full-size length} = \text{Model length} \times \text{Scale factor} \]

Substituting the values:

\[ \text{Full-size length} = 8 , \text{cm} \times 5 , \text{m/cm} = 40 , \text{meters} \]

Therefore, the full-size boat is 40 meters long.
