To find the volume of the pyramid-shaped bottle, we can use the formula for the volume of a pyramid:

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

where:

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

First, we'll calculate the area of the base. The base is a rectangle with a length of 15 cm and a width of 8 cm:

\[ B = \text{length} \times \text{width} = 15 , \text{cm} \times 8 , \text{cm} = 120 , \text{cm}^2 \]

Now we can substitute the values into the volume formula. The height of the pyramid is given as 22 cm.

\[ V = \frac{1}{3} \times 120 , \text{cm}^2 \times 22 , \text{cm} \]

Calculating this step-by-step:

  1. Calculate \( \frac{1}{3} \times 120 \): \[ \frac{120}{3} = 40 \]

  2. Now multiply by the height \( 22 \): \[ V = 40 , \text{cm}^2 \times 22 , \text{cm} = 880 , \text{cm}^3 \]

Therefore, the new bottle will hold 880 cm³ of juice.
