Question

a cube of silver has a mass of 21 kg. calculate the length of the cube's side in inches. the density of silver is 10.49 g/cm3.

Answer 1

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
