We have to find the volue of the prism.
The base of the prism is a rectangle.
Hence the area of the base given by
A=lb.
Here l= 12 in and b=24 in
Since the answer is in feet, we have to convert inches into feet.
We know that 1 feet = 12 inches.
Hence l= 1 feet and b=2 feet.
Hence the area of the base is
Now the volume of the prism is
Note that 18 inches=1.5 feet.
