- Given that - The block weighs 780g
therefore ,
[tex]\bold\blue{mass \: = 780g}\\[/tex]
[tex]\bold\green{----------------}[/tex]
- Now ,
dimensions of the given block are
2 cm × 5 cm × 6 cm
[tex]\bold\purple{Volume = l \times b \times h }\\\\ \bold \purple{⇢ (2 \times 5 \times 6) \: cm {}^{3}} \\\\\bold\purple{ ⇢60cm {}^{3}} [/tex]
therefore ,
[tex]\bold\blue{Volume = 60cm {}^{3}} [/tex]
[tex]\bold\green{----------------}[/tex]
- Further ,
[tex]\bold\pink{Density = \frac{mass}{volume} }\\ \\ \bold\pink{ ⇢ \cancel\frac{780 \: g}{60 \: cm {}^{3} } } \\ \\ \bold\pink{⇢13g \: cm {}^{ - 3} }[/tex]
therefore ,
[tex]\bold\blue{Density \: = 13 \: g \: cm {}^{ - 3} }[/tex]
hope helpful~
The mass, volume and density of the block of metal are 780 grams, 60 cm³ and 13 g/cm respectively
Volume of a rectangular prism
volume = lwh
where
- l = length
- w = width
- h = height
Therefore,
volume = 6 × 5 × 2 = 60 cm³
Therefore,
mass = 780 grams
volume = 60 cm³
density = mass / volume
density = 780 / 60
density = 13 grams per centimetre
