Question

The formula for volume of cube is:

• A. $l^3$
• B. $6l^2$
• C. $4l^3$
• D. $6l^3$

Answer 1

The correct option is A $l^3$

Let $l$ be the length of side of the cube.

We know, a cube is a cuboid whose length, breadth and height are all equal.

That is, $l=b=h$.

Then,

$\text{Volume}=\text{length}\times \text{breadth}\times \text{height}$

$\Rightarrow$Volume of cube $=l\times l\times l$

$\therefore$ Volume of cube $=l^3$.

So, option $A$ is correct.
