Question

A block of metal has dimensions of 2 cm by 5 cm by 6 cm. The block weighs 780 g. From this information, calculate the mass, volume and density.

Answer 1

$\huge\fbox{Answer ☘}$

• Given that - The block weighs 780g

therefore ,

$\bold\blue{mass \: = 780g}$

$\bold\green{----------------}$

• Now ,

dimensions of the given block are

‎ ‎ ‎ ‎ ‎‎ ‎ ‎ ‎ ‎‎ ‎ ‎ ‎ ‎‎ ‎ ‎ ‎ ‎‎ ‎ ‎ ‎ ‎‎ ‎ ‎ ‎ ‎‎ ‎ ‎ 2 cm × 5 cm × 6 cm

$\bold\purple{Volume = l \times b \times h }\\\\ \bold \purple{⇢ (2 \times 5 \times 6) \: cm {}^{3}} \\\\\bold\purple{ ⇢60cm {}^{3}}$

therefore ,

$\bold\blue{Volume = 60cm {}^{3}}$

$\bold\green{----------------}$

• Further ,

$\bold\pink{Density = \frac{mass}{volume} }\\ \\ \bold\pink{ ⇢ \cancel\frac{780 \: g}{60 \: cm {}^{3} } } \\ \\ \bold\pink{⇢13g \: cm {}^{ - 3} }$

therefore ,

$\bold\blue{Density \: = 13 \: g \: cm {}^{ - 3} }$

hope helpful~

Answer 2

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
