# Find the Volume in Cubic Decimetre of the Cube Whose Side is 75 Cm. - Mathematics

Find the volume in cubic decimetre of the cube whose side is 75 cm.

#### Solution

Side of the cube = 75 cm

$= 75 \times \frac{1}{10} dm ( \because 1 dm = 10 cm)$

$= 7 . 5 dm$

$\therefore \text { Volume of the cube = (side ) }^3 = (7 . 5 )^3 = 421 . 875 {dm}^3$

Is there an error in this question or solution?
