How did the mass of the car change after 50 dry pine blocks with a volume of 20 dm3 each were loaded into it?

Given:

n = 50 – the number of pine blocks that were loaded into the vehicle;

V = 20 cubic decimeters – the volume of each bar;

ro = 500 kilograms / cubic meter – density of dry pine.

It is required to determine dm (kilogram) – how the mass of the car will change after pine blocks are loaded into it.

Let’s translate the units of measurement of volume in the SI system:

V = 20 dm3 = 20 * 10-3 = 20/1000 = 0.02 cubic meters.

Then the total volume of pine blocks will be equal to:

V1 = V * n = 0.02 * 50 = 1 m3.

The mass will be equal to:

dm = ro * V1 = 500 * 1 = 500 kilograms.

Answer: after loading pine blocks, the vehicle weight will increase by 500 kilograms.
