Enter dimensions to calculate volume. Supports sphere, cube, cuboid, cylinder, cone, frustum, and prism shapes.
Sphere volume: V = 4/3 pi r^3. Example: sphere radius 3cm has volume approx 4/3 x pi x 27 approx 113.1 cm^3.
Cylinder volume = base area x height = pi r^2 h.
Cone volume = 1/3 x base area x height = 1/3 x pi r^2 h. One-third of a cylinder with same base and height.
Frustum volume = 1/3 pi h(R^2 + Rr + r^2), where R = bottom radius, r = top radius, h = height.
Triangular prism volume = base triangle area x prism length/height.
