Find the mass of 1 m3 of concrete block for the foundation if one block with dimensions of 1.5 m

Find the mass of 1 m3 of concrete block for the foundation if one block with dimensions of 1.5 m, 4 dm and 60 cm has a mass of 900 kg.

We translate the overall dimensions of the block into one size.

4 dm = 4/10 = 0.4 m.

60 cm = 60/100 = 0.6 m.

Determine the volume of this block.

We multiply all its sizes among ourselves.

We get:

1.5 * 0.6 * 0.4 = 0.36 m2

We make the proportion in which 900 kg of the mass of a given block are related to its area, just as the unknown weight x is related to 1.

Will be:

900 / 0.36 = x / 1.

0.36 * x = 900.

x = 900 / 0.36 = 2500 kg.

Answer:

The block weighs 2500 kg.
