Answer 1

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

\[
\text{Volume} = \frac{1}{3} \times \text{Base Area} \times \text{Height}
\]

In this case, the base of the pyramid is a square with each side measuring 112 feet, and the height (altitude) is 71 feet.

**Step 1: Calculate the Base Area**

The area of the base (which is a square) can be calculated as:

\[
\text{Base Area} = \text{side} \times \text{side} = 112 \, \text{feet} \times 112 \, \text{feet} = 12,544 \, \text{ft}^2
\]

**Step 2: Calculate the Volume**

Now, substitute the base area and height into the volume formula:

\[
\text{Volume} = \frac{1}{3} \times 12,544 \, \text{ft}^2 \times 71 \, \text{feet}
\]

Calculating that:

\[
\text{Volume} = \frac{1}{3} \times 12,544 \times 71 = \frac{890,624}{3} \, \text{ft}^3 \approx 296,874.67 \, \text{ft}^3
\]

Thus, the volume of the pyramid at the Louvre Museum is approximately **296,874.67 ft³**.

So the correct response is:

**296,874.67 ft³**.
