To find the volume \( V \) of a rectangular pyramid, you can use the formula:

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

where \( B \) is the area of the base and \( h \) is the height of the pyramid.

In this problem:

  • The area of the base \( B \) is given as 200 square meters.
  • The height \( h \) is given as 75 meters.

Now, we can substitute these values into the formula:

\[ V = \frac{1}{3} \times 200 , \text{m}^2 \times 75 , \text{m} \]

Now, let's calculate \( V \):

  1. Multiply the base area by the height: \[ 200 , \text{m}^2 \times 75 , \text{m} = 15000 , \text{m}^3 \]

  2. Now, multiply this result by \( \frac{1}{3} \): \[ V = \frac{1}{3} \times 15000 , \text{m}^3 = 5000 , \text{m}^3 \]

So, the volume of the rectangular pyramid is:

\[ \boxed{5000} , \text{cubic meters} \]
