### How to calculate the volume & weight of a concrete cube?

Let us go through the procedure to calculate the volume & weight of the standard concrete cubes used in the lab. testing.

Given data:

Dimension of the cube

= 150mm. × 150mm. × 150mm.

= 0.15m. × 0.15m. × 0.15m.

1. Volume of the cube is calculated  by the formula

= [length × breadth × height]

In any cube, all the 3 sides are equal

i.e. length = breadth = height = s

So, the volume of the concrete cube

= [0.15m. × 0.15m. × 0.15m.]

= 0.003375 CUM.

2. The weight of the concrete cube

= [density × volume.]

As you know, the density of concrete =2400kg / CUM.

The weight of the concrete cube

= [2400 kg./ CUM × 0.003375 CUM]

= 8.1kg.

Note:

1. The density of RCC = 2500kg./CUM &

2. The density of PCC = 2400kg. / CUM.

The concrete cube does not contain a reinforcement. So, its density will be 2400 kg / CUM.
