To find the width of the fish tank, you can use the formula for the volume of a right rectangular prism:
\[ \text{Volume} = \text{length} \times \text{width} \times \text{height} \]
You've been given:
- Volume = 1,920 cubic inches
- Height = 12 inches
- Length = 20 inches
Now, substitute the values into the volume formula:
\[ 1,920 = 20 \times \text{width} \times 12 \]
Next, multiply the length and height:
\[ 20 \times 12 = 240 \]
Now, the equation looks like this:
\[ 1,920 = 240 \times \text{width} \]
To find the width, divide both sides of the equation by 240:
\[ \text{width} = \frac{1,920}{240} \]
Calculating the right side:
\[ \text{width} = 8 \]
Therefore, the width of the tank is 8 inches.
