If the volume of a rectangular prism is 200 cubic units, and the area of the base is 16 square units, what is the height of the prism?

The height of the prism is 12.5 units.

Step-by-step explanation:

Volume formula:  V = (length)(width)(height)

or                           V = (area of base)(height)

Here, we want to calculate the height.  The appropriate formula is

(height) = (volume) / (area of base) = (200 units³) / (16 units²) = 12.5 units

The height of the prism is 12.5 units.

you can't solve x because it is 2 linear equation and you only have one equation
