To find the volume of a rectangular prism, you can use the formula:

\[ \text{Volume} = \text{Base Area} \times \text{Height} \]

Step 1: Calculate the Area of the Base

The area of the rectangular base can be calculated using the formula for the area of a rectangle:

\[ \text{Area} = \text{Length} \times \text{Width} \]

Given the dimensions of the base:

  • Length = 5 in
  • Width = 6 in

So the area of the base is:

\[ \text{Area} = 5 , \text{in} \times 6 , \text{in} = 30 , \text{in}^2 \]

Step 2: Height of the Prism

The height of the prism is given as:

\[ \text{Height} = 8 , \text{in} \]

Step 3: Calculate the Volume

Now we can find the volume using the area calculated and the height of the prism:

\[ \text{Volume} = \text{Base Area} \times \text{Height} = 30 , \text{in}^2 \times 8 , \text{in} \]

Calculating this gives:

\[ \text{Volume} = 240 , \text{in}^3 \]

Final Results:

  • Area of the base: \(30 , \text{in}^2\)
  • Height of the prism: \(8 , \text{in}\)
  • Volume: \(240 , \text{in}^3\)
