Question

find the density in the following.
1.You have a rock with a volume of 15cm and a mass of 45kg.
a) 3g/cc b) 5g/cc c)4g/cc d) 9g/cc
please explain it​

Answer 1

3gram.

ab mujhe explain karane nahin aata hai.

Answer 2

Answer:

3kg/cm³. ,, 3000g/cm³,,,,,. 3000000/m³

Explanation:

GIVEN---. MASS-45Kg

volume--15cm³

now we know that we have to find the density

Density=Mass/Volume

putting values in the above relation

Density=45kg/15cm³

= Density =3kg/cm³.

{when we divided 45 from 15 we get 3}

[and its respective units kg and cm³ come as they were before]

Density=3kg/cm³. -------- (I)

OR

(3×1000)g/cm³. Density= 3000g/cm³

. {here we changed the first equation by changing 3 kg into grams}

[when we change kg into Grams we multiply the unit by thousand]

OR

[3kg/cm³ ÷ 1/(100 ×100×100)]kg/m³

{. here we changed the first equation by changing the denominator cm³ into m³}

when we change cm³ into m³ we multiply it by 3 hundreds

[3kg/cm³ ×( 100×100×100)/1]kg/m³

{I reciprocaled &changed the divide sign

into multiply}

density =3000000kg/m³

[we had changed the centimetre cube into metre cube and Density is now in KG/ metre cube].

hope it helped you
