Answer:
To find the height of a three-dimensional object (such as a rectangular prism) when you know the base area and the volume, you can use the formula:
Volume = Base Area × Height
In your case, you have the base area as 147 square centimeters and the volume as 1323 cubic units (presumably cubic centimeters since you're using square centimeters for the base area).
So, you want to find the height:
Height = Volume / Base Area
Height = 1323 cm³ / 147 cm²
Height = 9 cm
The height of the object is 9 centimeters.
