Question

an object is a regular, rectangular, solid with dimensions of 2cm by 3cm by 2cm. it has a mass of 24g. what is its density?

Answer 1

Given:-

• Mass, m = 24g

• Dimension 2×3×2

To Find:-

• Density ,D

Solution:-

Firstly we calculate the volume of rectangular solid.

Vol.of solid = 2×3×2

→ vol.of solid = 12cm³

Now we know that density is defined as the mass per volume.

• D = m/v

Substitute the value we get

→ D = 24/12

→ D = 2g/cm³

Therefore, the density of the given solid is 2g/cm³.

Answer 2

Answer:

• The required density = 2g/cm³

Given:

• An object is a regular, rectangular, solid with dimensions of 2cm by 3cm by 2cm. It has a mass of 24g.

Need to find:

• The required density = ?

Solution:

Calculate volume of the solid:

❥︎ Volume of the solid = 2 × 3 × 2

❥︎ volume of the solid = 12cm³

Formula used here:

• Density = Mass / Volume of the solid

Putting the values:

➜ Required density = 24/12

➜ Required density = 2g/cm³

Therefore:

• The required density = 2g/cm³
