Question

A rectangular block of copper metal weight 64g the dimensions of the block are 8 cm 4 cm and 6 cm calculate the density of the block​

Answer 1

Answer:

Density = Mass/Volume

Volume of block = 8×4×6= 192

Density = 64/192 =0.33 ans

Answer 2

Given:-

•Weight of a rectsngular block of copper = 64g.

•Dimensions of the block are 8cm,4cm and 6cm.

To Find:-

•Calculate the density of the block =?

Solution:-

Given,

• Weight of rectangular block = 64g
• Length = 8cm
• Breadth=4cm
• Height=6cm

As we know that

$\sf \large \: density \: of \: block = \frac{mass \: of \: block}{volume \: of \: block}$

Now put the values

$\: \sf \implies \: density \: of \: block = \frac{64}{8 \times 4 \times 6} \\ \\ \: \sf \implies \: density \: of \: block = \frac{1}{3} g {cm}^{ - 3} \\ \\ \: \sf \implies \: density \: of \: block = 0.3g {cm}^{ - 3}$

$\sf \therefore \: hence \: density \: of \: the \: block \: is \: 0.3g {cm}^{ - 3}$
