The length breadth and height of an object are 20 cm 15 cm 25 cm. find the volume and density​

Complete Question:

The length, breadth and height of an object are 20 cm, 15 cm and 25 cm respectively. Its mass is 7 kg. Find its volume and density

a. Volume of cuboid = 7500 cm³

b. Density = 0.000933 Kg/cm³

Explanation:

Given the following data;

a. To find the volume of the object.

An object that has a length, breadth and height is a cuboid.

Mathematically, the volume of a cuboid is given by the formula;

Volume of cuboid = length * breadth * height

Substituting into the formula, we have;

Volume of cuboid = 20 * 15 * 25

Volume of cuboid = 7500 cm³

b. To find the density of the object;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

Substituting into the formula, we have;

Density = 0.000933 Kg/cm³

conservation of mass

mass before something happens = mass afterwards
