The Density of a Concrete Slab

What is the density of a concrete slab with a mass of 180kg, dimensions of 0.80m x 0.60m x 0.04m?

How can we calculate the density of the concrete slab?

Calculation and Final Answer:

The density of the concrete slab can be calculated by dividing its mass by its volume. After calculating the volume of the slab as 0.0192 cubic meters, the density comes out to be approximately 9375 kg/m³.

To find the density of the concrete slab, we need to use the formula: Density = Mass/Volume. In this case, the mass of the concrete slab is 180 kg, and the volume can be calculated using the formula: Volume = Length × Width × Height.

By substituting the given values, we find the volume to be 0.80m x 0.60m x 0.04m = 0.0192 cubic meters (m³). Now, applying the formula for density (Density = Mass/Volume), we divide the mass of the slab by its volume to find the density. Therefore, the density of the concrete slab is approximately 9375 kg/m³.

Explanation: The density of an object can be calculated using the formula: density = mass / volume. First, we need to calculate the volume of the concrete slab, which is a rectangle, so the volume is length * width * thickness. That gives us: 0.80m x 0.60m x 0.04m = 0.0192 cubic meters (m³). Now, using the given mass of the slab (180kg), we apply the density formula: density = 180kg / 0.0192m³ = approximately 9375 kg/m³.

It's important to note that the density of concrete can vary depending on factors such as the composition, aggregate used, water-cement ratio, and presence of additives. Understanding the density of concrete is crucial in construction as it determines the strength and overall quality of structures.
