To find the maximum volume of a rectangular prism (in this case, the container) we use the formula:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
Given the dimensions of the container are:
- Length = 30 inches
- Width = 22 inches
- Height = 20.8 inches
Substituting these values into the formula:
\[ \text{Volume} = 30 , \text{in} \times 22 , \text{in} \times 20.8 , \text{in} \]
Calculating step-by-step:
- First, calculate the area of the base (length × width):
\[ 30 \times 22 = 660 , \text{in}^2 \]
- Next, calculate the volume by multiplying the area by the height:
\[ 660 , \text{in}^2 \times 20.8 , \text{in} = 13,728 , \text{in}^3 \]
Thus, the maximum amount of water that the rectangular container can hold is
\[ \boxed{13,728 , \text{in}^3} \]
