The formula for volume depends on the shape of the object. Here are some common volume formulas:

• Cube: V=s3V=s^3V=s3 (where sss is the length of a side)
• Rectangular prism: V=l×w×hV=l\times w\times hV=l×w×h (length × width × height)
• Cylinder: V=πr2hV=\pi r^2hV=πr2h (where rrr is the radius of the base and hhh is the height)
• Sphere: V=43πr3V=\frac{4}{3}\pi r^3V=34​πr3
• Cone: V=13πr2hV=\frac{1}{3}\pi r^2hV=31​πr2h
• Pyramid: V=13Base Area×hV=\frac{1}{3}\text{Base Area}\times hV=31​Base Area×h

If you have a specific shape in mind, I can give you the exact formula!
