What is the volume in ml of a cube with each side 80mm long ?

512 mL

Explanation:

We are given;

A cube with a side 80 mm long or 8 cm long  

We are required to calculate the volume;

Volume refers to the amount of space an object occupies.To calculate the volume of a cube we get the cube of its side;That is, volume of the cube = l³

Therefore;

Volume = (8 cm)³

            = 512 cm³

But; 1 cm³ = 1 mL

Therefore, the volume of the cube in mL is 512 mL

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
