How do you calculate the volume of a 3D shape?

Volume measures 3D space occupied by an object. For a rectangular box, V = length × width × height. For a cylinder, V = π × radius² × height. For a sphere, V = (4/3) × π × radius³.

What is the SI unit for volume?

The official SI unit of volume is the cubic meter (m³). Commonly used metric sub-units include the liter (1,000 L = 1 m³) and cubic centimeter (cm³).

How do you calculate liquid volume in a horizontal cylindrical tank?

Use the circular segment formula: V = [r² arccos((r-d)/r) - (r-d)√(2rd - d²)] × L, where r is radius, d is liquid depth, and L is tank length.

How to Calculate Triangular Prism Volume

Understand the mathematical formula and measurement method

Standard Volume FormulaV = \frac{1}{2} b h l

Where b = triangle base, h = triangle height, and l = prism length.

Calculation Steps

1Measure base of the triangle (b) and height of the triangle (h).
2Calculate the triangular end area: A_tri = (1/2) × b × h.
3Multiply by the length of the prism (l): Volume = (1/2) × b × h × l.
