Volume Formulas Reference
CubeV = a³, SA = 6a²
Rectangular PrismV = l×w×h, SA = 2(lw + lh + wh)
SphereV = (4/3)πr³, SA = 4πr²
CylinderV = πr²h, SA = 2πr² + 2πrh
ConeV = (1/3)πr²h, SA = πr² + πrl
Square PyramidV = (1/3)l²h, SA = l² + 2l×slant
Frequently Asked Questions
What is the formula for the volume of a sphere?
The volume of a sphere is V = (4/3)πr³, where r is the radius. The surface area is 4πr².
How do I calculate the volume of a cylinder?
Volume of a cylinder = πr²h, where r is the base radius and h is the height. Surface area = 2πr² + 2πrh.
What is the difference between volume and surface area?
Volume measures the three-dimensional space inside a shape (cubic units). Surface area measures the total area of all outer surfaces of the shape (square units).
How do you find the volume of a pyramid?
Volume of a pyramid = (1/3) × base area × height. For a square pyramid: V = (1/3) × l² × h, where l is the base side length and h is the height.
What units are used for volume?
Volume is measured in cubic units: cm³, m³, mm³, in³, ft³, etc. Common conversions: 1 litre = 1000 cm³, 1 m³ = 1000 litres.
