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 $2.9\times 10^{-7}m^3$

Explanation :  Given,

Length of salt crystal = $2.44\times 10^{-2}m$

Breadth of salt crystal = $1.4\times 10^{-3}m$

Height of salt crystal = $8.4\times 10^{-3}m$

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:

$V=(2.44\times 10^{-2}m)\times (1.4\times 10^{-3}m)\times (8.4\times 10^{-3}m)=2.9\times 10^{-7}m^3$

Hence, the volume of salt crystal is $2.9\times 10^{-7}m^3$

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
