Respuesta :
volume = 30*30*30 = 27000 cm^3
density = 2.8 g/cm^3
mass = 27000*2.8 = 75600g = 75.6 kg
density = 2.8 g/cm^3
mass = 27000*2.8 = 75600g = 75.6 kg
The mass of the boulder is 75600 kg.
What is mass?
mass is the quantity of matter a body contains.
To calculate the mass of the boulder, we use the formula below.
Formula:
- D = m/v.............. Equation 1
Where:
- D = Density of the Boulder
- v = Volume of the Boulder
- m = mass of the Boulder
Make m the subject of the equation
- m = Dv............... Equation 2
From the question,
Given:
- D = 2.8 g/cm³
- v = l³ = 30³ = 27000 cm³
From the question,
- m = (2.8×27000)
- m = 75600 kg
Hence, the mass of the boulder is 75600 kg.
