The total volume of the given figure is 2,800 ft³ (that is the amount of soil needed to fill it).
How to get the volume of the figure?
To do it, we can separate the figure into two simpler ones.
We will have:
- A rectangular prism of 25ft by 20 ft by 5ft.
- A rectangular prism of 25ft by 4ft by 3ft
The volume of a rectangular prism is equal to the product between their dimensions, so the volumes of the prisms are:
[tex]V = 25ft*20ft*5ft = 2,500 ft^3[/tex]
[tex]V' = 25ft*4ft*3ft = 300ft^3[/tex]
Then the total volume is the sum of these:
[tex]v = 2,800 ft^3[/tex]
