Answer:
d = 4.50 g/cm³
Explanation:
Given data:
Edge length of a cube = 11.4 mm (11.4/10 = 1.14 cm)
Mass of cube = 6.67 g
Density = ?
Solution:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
First of all we will calculate the volume of cube.
Volume = length × width × height
Since all are equal,that's why
Volume = 1.14 cm × 1.14 cm × 1.14 cm
Volume = 1.482 cm³
d = m/v
d = 6.67 g/ 1.482 cm³
d = 4.50 g/cm³
