Enter dimensions and density to see weight calculationand step-by-step results.

Understanding Cuboid Weight Calculation

Formulas Used

V_cm³= L × W × H (Volume in cubic centimeters)

V_m³= V_cm³÷ 1,000,000 (Volume in cubic meters)

Weight = V_m³× ρ (Weight in kilograms)

Common Material Densities

Wood:400-800 kg/m³

Aluminum:2,700 kg/m³

Steel:7,850 kg/m³

Concrete:2,400 kg/m³

Plastic (PVC):1,400 kg/m³

Glass:2,500 kg/m³

Copper:8,960 kg/m³

Water:1,000 kg/m³

Example Calculation

Given:Length = 50 cm, Width = 40 cm, Height = 30 cm, Density = 800 kg/m³

Solution:

Volume (cm³) = 50 × 40 × 30 = 60,000 cm³

Volume (m³) = 60,000 ÷ 1,000,000 = 0.06 m³

Weight = 0.06 × 800 = 48 kg

Applications

Engineering:Calculate requirements and structural loads
Manufacturing:Estimate product weights for shipping and handling
Construction:Determine concrete, steel, and material quantities
Packaging:Calculate weights and costs
Design:Optimize material usage and weight distribution
