Calculate the weight and volume of cubes, cuboids and spheres

Calculate the weight or dimensions of a cube, cuboid or sphere. Check the help section for formulas, equations, and table of density for a wide variety of materials – from A for aluminum to Z for zinc.

At a Glance

The volume of a cuboid is calculated by multiplying the length by the width and the height of the cuboid.
To calculated the volume of a cube, take the edge length of the cube to the power of 3.
To determine the volume of a sphere, you have to take the diamater to the power of 3 and multiply it to Pi as well as 1/6.
The weight of an object is calculated by multiplying the volume by the density of the material.

To convert from density in kg/m³ to other density units use the converting values below:

1 kg/m3 = 0.001 kg/dm3 (kg/l) = 0.000001 kg/cm3 = 1 g/l = 0.001 g/ml = 0.0005780 oz/in3 = 0.16036 oz/gal (Imperial) = 0.1335 oz/gal (U.S.) = 0.0624 lb/ft3 = 0.000036127 lb/in3 = 1.6856 lb/yd3 = 0.010022 lb/gal (Imperial) = 0.008345 lb/gal (U.S) = 0.0007525 ton/yd3

Formulas for calculating the weight of an object

Formula: Calculation of the volume of a Cuboid

$\text{Volume of Cuboid}=\text{Length}\times\text{Width}\times\text{Height}$

The volume of a cuboid is calculated by multiplying the length by the width and height of the cuboid.

Formula: Calculation of the volume of a Cube

$\text{Volume of Cube}=\text{(Edge length)}^\text{3}$

To calculate the volume of a cube, it is sufficient to take the edge length of the cube to the power of 3.

Formula: Calculation of the volume of a Sphere

$\text{Volume of Sphere}=\frac{\text{1}}{\text{6}}\times\pi\times\text{(Diameter)}^\text{3}$

If you want to determine the volume of a sphere, you have to take the diameter to the power of three and multiply it with Pi as well as one sixth.

Formula: Calculation of the Weight of an Object

$\text{Weight of Object}=\text{Volume}\times\text{Density}$

The weight of an object is calculated by multiplying the volume by the density of the material.
