Calculate Base Area: Rectangular Prism with Volume 80 m³ and Height 4 m

To solve this problem, we'll follow these steps:

• Use the volume formula for the rectangular prism: $V = A_{\text{base}} \times h$.
• Rearrange the formula to solve for the base area: $A_{\text{base}} = \frac{V}{h}$.
• Substitute the given values into this rearranged formula.

Now, let's work through these steps:
Step 1: We know the volume $V = 80 \, \text{m}^3$ and the height $h = 4 \, \text{m}$.
Step 2: Using the formula $A_{\text{base}} = \frac{V}{h}$, we substitute the given numbers:
$A_{\text{base}} = \frac{80}{4} \, \text{m}^2$.
Step 3: Perform the division to find the area of the base:
$A_{\text{base}} = 20 \, \text{m}^2$.

Therefore, the area of the base of the rectangular prism is $20 \, \text{m}^2$.
