To calculate the volume of a right rectangular pyramid, you can use the formula:

\[
V = \frac{1}{3} \times B \times h
\]

where \( V \) is the volume, \( B \) is the area of the base, and \( h \) is the height (or altitude) of the pyramid.

1. First, calculate the area of the base \( B \):
- The area \( B \) of the rectangular base is given by the formula:
\[
B = \text{length} \times \text{width} = 6.75 \, \text{inches} \times 10.25 \, \text{inches}
\]

Calculating that gives:
\[
B = 6.75 \times 10.25 = 69.1875 \, \text{square inches}
\]

2. Now, substitute the area of the base and the height into the volume formula:
- The altitude (height) \( h \) is given as 22.3 inches.
\[
V = \frac{1}{3} \times 69.1875 \times 22.3
\]

Calculating \( V \):
\[
V = \frac{1}{3} \times 69.1875 \times 22.3 \approx \frac{1}{3} \times 1547.6875 \approx 515.8958333
\]

Rounding this to a reasonable number of decimal places (typically two for volume):
\[
V \approx 515.90 \, \text{cubic inches}
\]

Therefore, the volume of the pyramid is approximately **515.90 cubic inches**.

Let’s go through the calculations step by step again to ensure accuracy when calculating the volume of the pyramid.

The formula for the volume \( V \) of a right rectangular pyramid is:

\[
V = \frac{1}{3} \times B \times h
\]

where:
- \( B \) is the area of the base, and
- \( h \) is the height (altitude) of the pyramid.

### Step 1: Calculate the area of the base \( B \)

The base of the pyramid is a rectangle. The area \( B \) can be calculated as:

\[
B = \text{length} \times \text{width}
\]

Given:
- Length = 6.75 inches
- Width = 10.25 inches

Calculating the area:

\[
B = 6.75 \times 10.25 = 69.1875 \, \text{square inches}
\]

### Step 2: Substitute into the volume formula

Now, plug the area \( B \) and the height \( h \) into the volume formula. The given height \( h \) is 22.3 inches:

\[
V = \frac{1}{3} \times 69.1875 \times 22.3
\]

### Step 3: Perform the calculations

First, multiply the area of the base \( B \) by the height \( h \):

\[
69.1875 \times 22.3 \approx 1546.6875
\]

Now, divide by 3 to find the volume:

\[
V = \frac{1546.6875}{3} \approx 515.5625
\]

### Final Result

Thus, the volume of the pyramid is approximately:

\[
V \approx 515.56 \, \text{cubic inches}
\]

If you would like this rounded to two decimal places, it would be:

\[
\boxed{515.56 \, \text{cubic inches}}
\]

Let's re-evaluate the problem thoroughly to ensure the calculations are spot on.

The volume \( V \) of a right rectangular pyramid is given by the formula:

\[
V = \frac{1}{3} \times B \times h
\]

Where:
- \( B \) is the area of the base (which is a rectangle),
- \( h \) is the height of the pyramid.

### Step 1: Calculate the Area of the Base \( B \)

Given:
- Length = 6.75 inches
- Width = 10.25 inches

The area \( B \) of the rectangular base is calculated as:

\[
B = \text{length} \times \text{width} = 6.75 \, \text{inches} \times 10.25 \, \text{inches}
\]

Calculating that:

\[
B = 6.75 \times 10.25 = 69.1875 \, \text{square inches}
\]

### Step 2: Use the Height

The height of the pyramid \( h \) is given as 22.3 inches.

### Step 3: Plug Values into the Volume Formula

Substituting \( B \) and \( h \) into the volume formula:

\[
V = \frac{1}{3} \times 69.1875 \times 22.3
\]

Calculating the volume step-by-step:

1. Calculate \( 69.1875 \times 22.3 \):

\[
69.1875 \times 22.3 = 1547.6875
\]

2. Now divide by 3 to find the volume:

\[
V = \frac{1547.6875}{3} = 515.8958333
\]

### Final Result

Rounding to two decimal places, we find:

\[
V \approx 515.90 \, \text{cubic inches}
\]

Please let me know if there are any specifics that I may have misunderstood. The calculation for the volume is consistent, and 515.90 cubic inches should be correct based on the values provided. If there's a mistake in the values or expectations, please clarify!
