Question

find the density of object..​

Answer 1

Question -

• Find the density of an object of mass 200 kg and having length 5 m, breadth 4 m and height 2 m.

Answer -

• The density of the object = 5 kg/m³.

To find -

• The density of the object.

Step-by-step explanation -

• Before finding the density of the object, let's find it's volume!

We know that -

$\bigstar \: \underline{\boxed{\sf Volume_{(cuboid)} = L \times B \times H}}$

Where -

• L = Length.
• B = Breadth.
• H = Height.

Here -

• Length = 5 m.
• Breadth = 4 m.
• Height = 2 m.

Therefore -

$\bf \mapsto Volume_{(object)} = 5 \times 4 \times 2$

$\bf \mapsto Volume_{(object)} = 40 \: m^3$

________________________________

Now, we know that -

$\bigstar \: \underline{\boxed{\sf Density = \dfrac{Mass}{Volume}}}$

Here -

• Mass = 200 kg.
• Volume = 40 m³.

Therefore -

$\tt \dashrightarrow Density = \cancel{\dfrac{200}{40}}$

$\tt \dashrightarrow Density = 5 \: kg/m^3$

Hence -

• The density of the object is 5 kg/m³.
