Question

Find the mass of 150cm cube of a metal with density of 7.8g/cm cube.

Answer 1

Given

Find the mass of 150cm cube of a metal with density of 7.8g/cm cube.

Solution

$\large{\underline{\boxed{\tt{Density = \dfrac{Mass}{Volume}}}}}$

• Density = 7.8g/cm³
• Volume = 150cm³
• Mass = ?

Let the mass of metal be m

➪ Density = Mass/Volume

➪ 7.8 = m/150

➪ m = 7.8×150

➪ m = 1170g

$\large{\underline{\boxed{\tt{Mass\:metal = 1170g}}}}$

Answer 2

Answer: mass = 7.8 × 150

= 1170 g

= 1.17 kg
