Question

volume of cube is 64cm cube. find the length of its edge

Answer 1

Volume of cube = 64 cm^3

Edge of cube = cube root 64

= 4 cm

Answer 2

GIVEN:

VOLUME OF THE CUBE=$64cm$

TO FIND:

The length of its edge

SOLUTION:

The formula for volume of a cube (V)$=a^{2}$

where a is the edge length of the cube

$V=a^{3}\\\\64=a^{3}\\\\\\a=\sqrt[3]{64}\\a=4cm$

HENCE, the length of its edge is 4 cm

THEORY, a cube has  6 faces, 12 edges, and 8 vertices.
