Calculating the Total Mass of Concrete Slabs

What is the total mass of 60 concrete slabs with dimensions of 400mm by 400mm by 28mm and density of 2250kg/m³?

How can we calculate the total mass of 60 concrete slabs using the given dimensions and density?

Total Mass Calculation:

The total mass of 60 concrete slabs can be calculated by first converting the dimensions to meters, calculating the volume of one slab, finding the mass of one slab using the density, and then multiplying by the number of slabs.

Given the dimensions of the concrete slab as 400mm by 400mm by 28mm and the density of the concrete as 2250kg/m³, we can proceed with the calculation to find the total mass of 60 slabs.

Step 1: Convert dimensions to meters:

400 mm = 0.400 m

400 mm = 0.400 m

28 mm = 0.028 m

Step 2: Calculate the volume of one slab:

Volume (V) = length × width × height

V = 0.400 m × 0.400 m × 0.028 m

V = 0.00448 m³

Step 3: Calculate the mass of one slab using the density:

Mass = density × volume

Mass = 2250 kg/m³ × 0.00448 m³

Mass = 10.08 kg

Step 4: Calculate the total mass of 60 concrete slabs:

Total Mass = Mass of one slab × Number of slabs

Total Mass = 10.08 kg × 60

Total Mass = 604.8 kg

Therefore, the total mass of 60 concrete slabs with dimensions of 400mm by 400mm by 28mm and density of 2250kg/m³ is 604.8 kg.
