Question

A piece of wood of mass 100 g has a volume of 300 cm
Find the density of wood in i. C.G.S. unit and ii. S.I. unit

Answer 1

Answer:

density

cgs=> 0.3g/cm³

si => 333.33kg/m³

Explanation:

density = mass ÷ volume

density = 100/300 = (1/3)g/cm³

in SI unit,

mass = 0.1kg

volume = 300 ÷ 10⁶

density = 0.1 ÷ (300÷10⁶)

=> density = 0.1×10⁶ ÷ 300 = 1000/3

=> density = 333.33kg/m³

Answer 2

Explanation:

I) density = mass/ volume

= 100/300

= 1/3 gm/cm^3

ii) density = mass/volume

= (100/1000)/(300/1000000)

= 1000/3 kg /m^3
