Volume Formulas for Rectangular Prisms and Cubes
Volume formulas for rectangular prisms and cubes is a Grade 6 geometry skill in Big Ideas Math Advanced 1, Chapter 8: Surface Area and Volume. The volume of a rectangular prism is V = l x w x h (length times width times height), and a cube uses V = s^3 (side cubed). Volume is measured in cubic units and represents the amount of space inside a 3D figure.

Common Questions
What is the formula for the volume of a rectangular prism?
The volume of a rectangular prism is V = l x w x h, where l is the length, w is the width, and h is the height. All three dimensions must be in the same unit before calculating.
What is the formula for the volume of a cube?
Since all sides of a cube are equal, the volume formula is V = s^3, where s is the length of one side. This is the same as s x s x s.
What units are used for volume?
Volume is measured in cubic units: cubic inches (in^3), cubic feet (ft^3), cubic centimeters (cm^3), cubic meters (m^3), etc. The cubic unit represents a cube with sides of length 1 in that unit.
Where are volume formulas taught in Big Ideas Math Advanced 1?
Volume formulas for rectangular prisms and cubes are covered in Chapter 8: Surface Area and Volume of Big Ideas Math Advanced 1, the Grade 6 math textbook.
