Final answer:
To determine the weight of a solid block of granite with a given volume and density, calculate the mass by multiplying density and volume, then multiply the mass by the acceleration due to gravity to get the weight in Newtons and convert to kiloNewtons.
Step-by-step explanation:
The question is about calculating the weight of a block of granite knowing its volume and density. First, we find the volume of the granite block by multiplying its dimensions (1m x 1m x 2m), resulting in a volume of 2.0 m³. Then, given the density of granite (2700 kg/m³), we can calculate the mass by multiplying the density with the volume (mass = density × volume), which gives us a mass of 2700 kg/m³ × 2.0 m³ = 5400 kg. The weight (W) is calculated by multiplying the mass (m) by the acceleration due to gravity (g), W = m × g, leading us to a weight of 5400 kg × 10 m/s² = 54000 N or 54 kN as 1 kN = 1000 N.
