Question

the volume of a metal cube is 125 cubic cm when the density of a metal I 13.6g/cubic cm



find the mass of a metal cube in kilograms​

Answer 1

Given

• Volume of a metal cube is 125 cubic cm
• The density of a metal I 13.6g/cubic cm

We Find

• Mass of a metal cube in kilograms

We know That

• If we multiply the volume of a metal cube and density of a metal. so, we knows mass of a metal cube.

According to the question

Mass of a metal cube = volume of a metal cube × density of a metal ( per cubic CM )

Mass of a metal cube = 125 × 13.6 g /cubic cm

Mass of a metal cube = 1698 g /cubic cm

We convert into kg

kg = value in g / 1000

kg = 1698 / 1000

kg = 1.7 ( Approximately )

So, Mass of a metal cube in kilograms is 1.7 kg.

Answer 2

Density = mass/volume
13.6g/cm^3x 125 cm^3 =mass
1700g = mass
1.7 kg= mass
