To find the volume of Nicol's watermelon slice, which approximates the shape of a rectangular pyramid, we can use the formula for the volume of a pyramid:

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

First, we need to determine the base area. The base is a rectangle, and its area can be calculated using the formula for the area of a rectangle:

\[ \text{Base Area} = \text{width} \times \text{length} \]

Given:

  • Width = 1.1 inches
  • Length = 105 inches
  • Height = 8 inches

Let's calculate the base area:

\[ \text{Base Area} = 1.1 , \text{inches} \times 105 , \text{inches} = 115.5 , \text{inches}^2 \]

Now, we can use the base area to find the volume:

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

Substituting the values we have:

\[ V = \frac{1}{3} \times 115.5 , \text{inches}^2 \times 8 , \text{inches} \]

Calculating it step-by-step:

  1. Calculate the product of base area and height:

\[ 115.5 , \text{inches}^2 \times 8 , \text{inches} = 924 , \text{inches}^3 \]

  1. Now calculate the volume:

\[ V = \frac{1}{3} \times 924 , \text{inches}^3 = 308 , \text{inches}^3 \]

So, the approximate volume of Nicol's watermelon slice is:

\[ \boxed{308 , \text{inches}^3} \]
