Question

What is the volume of a salt crystal measuring 2.44 × 10–2 m by 1.4 × 10–3 m by 8.4 × 10–3 m?

Answer 1

Answer: The volume of salt crystal is
`2.9* 10^(-7)m^3`

Explanation : Given,

Length of salt crystal =
`2.44* 10^(-2)m`

Breadth of salt crystal =
`1.4* 10^(-3)m`

Height of salt crystal =
`8.4* 10^(-3)m`

To calculate the volume of salt crystal by using the formula of volume of cuboid, we use the equation:

`V=lbh`

where,

V = volume

l = length

b = breadth

h = height

Putting values in above equation, we get:

`V=(2.44* 10^(-2)m)* (1.4* 10^(-3)m)* (8.4* 10^(-3)m)=2.9* 10^(-7)m^3`

Hence, the volume of salt crystal is
`2.9* 10^(-7)m^3`

Answer 2

All solids have an orderly internal structure with repeating bonding patterns between atoms, ions, or molecules. They are called crystal lattices. They are a 3-dimensional arrangement of atoms inside a crystal. The volume of this crystal is:

Volume = 2.44 × 10^–2 m x 1.4 × 10^–3 m x 8.4 × 10^–3 m = 2.87 x 10^-7 m^3
