Question

the volume of a cube is 343 cm cube find the length of an edge of cube

Answer 1

hello!!

here's ur answer...

given that the volume of cube=343cm³

side³=343cm³

side=³√343

side=7cm

verification:-

volume of cube=side³

=7×7×7

=343cm³

hence, verified.

the length of the edge of cube is 7cm.

hope this helps....

Answer 2

GIVEN,

Volume of cube= 343cm³

TO FIND,

length of an edge of a cube.

SOLUTION,

a cube is a 3d-structure with equal height, length, and breadth.

here we are given

that the volume of a cube is 343cm³

and we know that volume of a cube = a³ ( where a = side of the cube)

∴ volume of cube= 343cm³

According to the problem,

        ⇒ a³= 343

        ⇒ a = ∛343

         ⇒ a = 7cm

HENCE THE LENGTH OF AN EDGE OF A CUBE IS 7CM.
