Most problems addressed by the technological design process have only one solution. This statement is also <em>False.</em> There is more than one way to skin a cat.
Density- It is a measurement of that how material is packed together tightly.
Its formula is ρ=m/v
where ρ is the density of material
m is the mass
v is the volume
here we have to find the length of cube's side
a cube of silver has a mass = 21 kg. = 21×10³ [∵1kg = 1000g ]
density of silver = 10.49g/cm³
the length of the cube's side = ?
v=m/ρ
l³ = 21×10³ /10.49 ≈ 2×10³ cm³
l =∛(2×10³)cm³
l = 1.26 ×10 = 12.6 cm
l = 4.96 inches [∵ 1 cm = 0.394 inch ]
the length of the cube's side is 4.96 inches
