Question

The volume of a cube is 15.625cm3. Find the length of its edge

Answer 1

The edge of cube is: 2.5 cm

Step-by-step explanation:

Let V be the volume of cube

V = 15.625 cm^3

Let x be the side of the cube then

$V = x^3\\15.625 = x^3$

Taking cube root on both sides

$\sqrt[3]{x^3} = \sqrt[3]{15.625} \\x = 2.5\ cm$

The edge of cube is: 2.5 cm
