Regular Solids
For regular solids like cubes, prisms, cylinders, cones, or spheres, calculating the volume involves using a formula that corresponds to the shape of the solid. The first step is to identify the shape of the solid and measure its defining dimensions, such as length, width, and height. Then, apply the appropriate formula to find the volume.
Volume Calculation For Regular Solids:
| Shape of Solid | Volume Formula |
|---|---|
| Cube | Volume = side length3 |
| Prism | Volume = base area × height |
| Cylinder | Volume = πr2h |
| Cone | Volume = (1/3)πr2h |
| Sphere | Volume = (4/3)πr3 |
Irregular Solids
Measuring the volume of irregular solids requires a different approach, commonly using the displacement of a liquid method. To determine the volume of an irregular solid, follow these steps:
- Submerge the solid in a liquid.
- Measure the volume of the liquid displaced.
- The volume of the solid is equal to the volume of the liquid displaced.
By submerging the irregular solid in water and recording the volume of water displaced, you can accurately measure the volume of unconventional shapes or objects.
Tools for Measuring Volume
The immersion method using a graduated cylinder is a common technique when measuring the volume of solid objects. This method provides accurate results, especially for irregular shapes.
Steps To Measure Volume With A Graduated Cylinder:
- Fill the graduated cylinder with water.
- Record the initial volume of water.
- Submerge the solid in the water.
- Record the final volume of water and calculate the difference.
The volume of the solid is equivalent to the change in volume of the water in the graduated cylinder.

Summary
Measuring the volume of a solid involves different approaches based on the shape of the solid. Regular solids can be measured using specific volume formulas, while irregular solids typically rely on the displacement method. By using appropriate tools such as graduated cylinders, you can accurately determine the volume of a solid object for various applications in mathematics and science.
Frequently Asked Questions
How Do You Calculate The Volume Of A Solid?
To calculate the volume of a solid, you can use the following formula: Volume = length × width × height. For regular-shaped objects, measure the dimensions (length, width, and height). For irregular objects, submerge the object in water and measure the volume of the displaced water using a graduated cylinder.
How Do You Measure The Volume Of Solid Figures?
To measure the volume of solid figures, measure the dimensions (length, width, height) for regular shapes. For irregular shapes, submerge in water and measure the displaced water volume using a graduated cylinder. You can also use the formula Volume = length × width × height for regular shaped solids.
What Are 2 Methods For Measuring Volume Of A Solid?
Two methods for measuring volume of a solid are by using dimensions (length, width, height) for regular shapes and water displacement for irregular objects.
