Answer :

Step-by-step explanation:

The formula to find the volume of a rectangular prism is:    where: -  is the length -  is the width -  is the height  Given: - Length (l) = 78 in - Width (w) = 18 in - Height (h) = 10 in  Substitute the values into the formula:      Therefore, the volume of the shaded solid below is 14,040 cubic inches.  If there are different shapes or dimensions, the volume calculation may vary based on the geometry of the solid. Let me know if you need further clarification or if the dimensions are different.
