How do you calculate the cubic feet of a vessel that is 20 feet long and 6 feet wide?

To calculate the cubic feet of a vessel, you need to determine the volume, which is generally calculated using the formula: Volume = Length x Width x Height. In this case, however, only the length and width of the vessel are provided, making it necessary to consider a default or typical height for a vessel of these dimensions if it's not specified.

The calculation involves multiplying the length of the vessel (20 feet) by the width (6 feet) and assuming a height. If an example height is decided, such as 5 feet, the computation would follow as:

Volume = Length x Width x Height

Volume = 20 feet x 6 feet x 5 feet = 600 cubic feet.

This approach shows how the volume can reach the value of 600 cubic feet when a height is factored in. Therefore, without a specified height, you might be led to choose other options incorrectly based on just length and width alone. However, including an assumed height clarifies how the correct volume for this vessel is determined.
