Question

The volume of a particular cube is numerically equal to its total surface area of. Calculate the length of one edge of the cube.

• A. $6$
• B. $8$
• C. $10$
• D. $12$

Answer 1

The correct option is A $6$

Given volume of a particular cube is numerically equal to its total surface area of it.
Let edge of cube be $x$
Formula of volume of cube is side${}^3$.
Formula for total surface area is $6$ side${}^2$.
As per question, length of one side or edge will be
$6$ side ${}^2=$ side${}^3$
$\therefore$ side $=6$
Length of one edge of cube will be $6$.
