Volume Formula Reference
Cube V = s³ SA = 6s²
Box/Prism V = l × w × h SA = 2(lw+lh+wh)
Cylinder V = π r² h SA = 2πr(r+h)
Sphere V = (4/3)πr³ SA = 4πr²
Cone V = (1/3)πr²h SA = πr(r+slant)
Tri. Prism V = (½bh)×length SA = 2(½bh)+l(b+h+hyp)
Frequently Asked Questions
How do I calculate the volume of a cylinder?
Volume = π × r² × h, where r is radius and h is height. A cylinder with radius 2m and height 5m: V = 3.14159 × 4 × 5 = 62.83 m³. Common use: estimating water tank or pool capacity.
How do I calculate the volume of a sphere?
Volume = (4/3) × π × r³. A sphere with radius 3m: V = (4/3) × 3.14159 × 27 = 113.1 m³. A sphere with radius 10cm: V = (4/3) × π × 0.001 = 0.00419 m³ = 4.19 litres.
How do I calculate the volume of a rectangular box?
Volume = Length × Width × Height. A box 2m × 1.5m × 1m = 3 m³. In feet: a 6ft × 4ft × 3ft box = 72 cubic feet. To convert cubic feet to litres: multiply by 28.317 (72 cu ft ≈ 2,039 litres).
