Question

Calculate the edge of the cube if its volume is 1331 cm.​

Answer 1

Given,

Volume =1331cm³

Volume of cube =a³

here a = edge

1331=a³

a= ³√1331 (cube root of 1331)

Therefore a=11cm

Answer 2

Answer:

11 is edge

Let the edge of the cube be a  

The volume of a cube = a × a × a

1331= a × a × a

a^3 = 1331

cube rooting on both side

cube root of a^3 = cube root of 1331

a = 11

as 1331 is the cube of  11

Therefore,  

Edge of a cube is 11 cm

Step-by-step explanation:Let the edge of the cube be a  

The volume of a cube = a × a × a

1331= a × a × a

a^3 = 1331

cube rooting on both side

cube root of a^3 = cube root of 1331

a = 11

as 1331 is the cube of 11.

Therefore,  

Edge of a cube is 11 cm
