How to Calculate Volume of 3D Shapes in Volume Unit

What is 3D Shapes?

3D shapes are solid objects that have three dimensions - length, width, and height. Examples of 3D shapes are cubes, pyramids, prisms, and spheres. 3D shapes have faces, edges, and vertices. A face is a flat surface, an edge is a line segment where two faces meet, and a vertex is a corner where three or more faces meet.

How to Calculate Volume of 3D Shapes in Volume Unit

To calculate the volume of a 3D shape in volume unit, you need to know the formula for the shape. Different shapes have different formulas, so you need to know the formula for the shape you are trying to calculate the volume for. For example, the formula for a cube is V = s³, where V is the volume and s is the length of one side.

Once you know the formula for the shape, you can calculate the volume. To do this, you need to plug the length, width, and height of the shape into the formula. If you are calculating the volume of a cube, you only need to plug in the length of one side. Then, you can multiply the numbers together to get the volume of the 3D shape in volume unit.

Examples

Cube

Let's say you have a cube with a length of 4 inches. To calculate the volume of the cube, you need to plug the length of one side (4 inches) into the formula V = s³. So, the volume of this cube is 4³ = 64 inches³.

Cylinder

Let's say you have a cylinder with a radius of 4 inches and a height of 6 inches. To calculate the volume of the cylinder, you need to plug the radius and height into the formula V = πr²h. So, the volume of this cylinder is π(4²)6 = 301.59 inches³.

Conclusion

To calculate the volume of a 3D shape in volume unit, you need to know the formula for the shape and plug the length, width, and height of the shape into the formula. Then, you can multiply the numbers together to get the volume of the 3D shape in volume unit.
