In a vertical cylinder, which measurement must be obtained after the area?

In the context of a vertical cylinder, obtaining the depth measurement after determining the area is crucial for calculating the total volume of the cylinder. The area alone provides the cross-sectional dimensions of the cylinder, but it is only when the depth (or height) measurement is obtained that one can accurately compute the overall volume using the formula Volume = Area x Depth.

Depth represents how tall the water column is within the cylinder, directly affecting the total volume of water it can hold. Hence, calculating the volume is solely dependent on both the area and the depth, making the depth an essential measurement following the area. Without knowing the depth, the volume remains indeterminate, regardless of the area calculated.
