What is the volume of a salt crystal measuring 5.44 x 10 ^ - 2 m by 2.5 x 10 ^ - 3 m by 7.9 x10-^ 3 m ?

The volume of a salt crystal with the mentioned dimensions is V= 107.44 x 10^-8.

Explanation:

To solve this problem we multiply the length of the sides of the crystal. To calculate this product you have to calculate:

1) (5.44 x 2.5 x 9,9). and

2) (10^-2 x 10^-3 x 10^-3). Here we have the product of powers of equal base so we should sum the exponents.

⇒(10^-2 x 10^-3 x 10^-3) = 10^(-2 + -3 + -3) ⇒ (10^-2 x 10^-3 x 10^-3) = 10^-8.

Finally,

V= (5.44 x 10^-2)x (2.3 x 10^-3) x (7.9 x 10^-3) ⇒ V= 107.44 x 10^-8 m.
