The mass of a 4 m3 plug is 0.8 t. Calculate the volume of a plug with a mass of 1.2 t.

It is known from the condition that the mass of a 4 m3 plug is 0.8 tons. In order to calculate the volume of a plug weighing 1.2 tons, we will compose and solve the proportion.

Let’s start by defining the volume of a plug with a mass of 1.2 tons using the variable x m3.

Let’s make the proportion:

4 m3 of cork – 0.8 tons;

x m3 plugs – 1.2 tons.

We got the proportion:

4 / x = 0.8 / 1.2;

We are looking for the unknown middle term of the proportion. To do this, we divide the product of the extreme terms of the proportion by the known average:

x = (4 * 1.2) /0.8 = 4.8 / 0.8 = 6 m3 plug.
