Question

Write in the form of an algebraic expression:
iv) Surface area of a cube is six times the square of its edge

Answer 1

Step: Write the algebraic expression
Let the surface area of the cube be $S$ and the length of edge be $a$.
$\text{Surface area of a cube}=6(\text{edge}{)}^2$
$\therefore S=6a^2$.
Hence, the required expression is $S=6a^2$ .
