The mass of 150 m³ of concrete is 360,000 kg.

Step-by-step calculation

  • Given density ρ=2400 kg/m3\rho =2400,\text{kg/m}^3ρ=2400kg/m3, which is a typical value for normal concrete.
  • Given volume V=150 m3V=150,\text{m}^3V=150m3.
  • Use the relationship mass=ρ×V\text{mass}=\rho \times Vmass=ρ×V.
  • So, mass=2400×150=360,000 kg\text{mass}=2400\times 150=360{,}000,\text{kg}mass=2400×150=360,000kg.

Answer: 360,000 kilograms of concrete.
