Measure the object’s dimensions
Identify the object’s shape
Use the correct volume formula
For rectangular objects, multiply length × width × height
For cubes, use side × side × side
For cylinders, use π × radius² × height
For spheres, use 4/3 × π × radius³
For cones, use 1/3 × π × radius² × height
For irregular objects, use water displacement
Record the volume in cubic units
Check that all measurements use the same unit before calculating
