# How do you find the volume of solid figures?

To find the volume of solid figures, use the length, width and height of the object, if its sides are measurable. If the figure has an irregular shape, measure its volume in terms of the volume of water it displaces using an overflow can and a graduated cylinder or beaker.

Continue ReadingIn case of a figure with a regular shape, determine its length, width and height using a measuring tape or ruler. Multiply the three measurements together to obtain the figure's volume in cubic units. If the figure is shaped irregularly, pour water in an empty overflow can to the brim. Allow the excess water to flow out via the downspout. Place a graduated cylinder beneath the can's spout.

Slowly, put the solid figure in the overflow can. This causes water displacement and the displaced water spills into the graduated cylinder.

Read the volume of the water in the cylinder. This equals the volume of the solid figure. Alternatively, pour water into a graduated beaker, and read the initial volume. The quantity of water filled should be such that it does not overflow when the figure is placed in the beaker.

Now, place the solid figure in the beaker. The water level should rise owing to displacement. Read the final volume of water. Subtract the initial water volume from the final one to obtain the solid figure's volume.
