What is the formula for calculating volume of a solid

Volume = length × width × height

Explanation:

Volume of solid:

It can be define as the space occupied by a solid  object is its volume.

The volume of solid is calculated through given formula:

Volume = length × width × height

Its SI unit is cubic meter.

For example:

The length of an solid object is 2 cm, height is 3 cm and width is 2 cm. What would be the volume of given object?

Formula:

Volume = length × width × height

Volume = 2cm × 2cm × 3cm

Volume = 12 cm³

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
