Question

The volume of a cubical box is 91125 cm3. Find the length of a side of the box.

Answer 1

$volume = 91125cm {}^{3} \\ a {}^{3} = 91125cm {}^{3} \\ a = \sqrt[3]{91125} \\ a = 45$
So, the length of the side of the cube is 45cm.

Answer 2

volume of cube = ( side )3

91125cm3. = (side) 3

45 cm = side .

hence , the length of side =45cm.
