Question

Find the length of the edge of a cube whose volume is 1728cubic cm.

Answer 1

We know that the volume of a cube is give by a^3, where a is the length of the edge. 

We also know that the volume of this cube is 172 cubic cm.

So, here, a^3 = 1728
a = cube root of 1728
a = 12 cm

So, the length of the edge is 12 cm

Answer 2

Answer:

We know that the volume of a cube is given by a³ , where (a) is the length of the edge

Given ,

Volume of the cube = 1720 cubic cm

Now ,

a³=1720

a=1720=12×12×12

a=12 cm

Hence, the length of the edge is 12cm
