V=(1/3)(area of the base)(<span>altitude)
V=</span><span>(1/3)(</span>6²)(6)= 72 m³
It is called a complex number.

Let , a, b and c be the length of three sides of triangle, represented in terms of vectors as
.
Now, vector of same Magnitude acts as normal vector to each side.
So, equation of any vector p having normal q is given by

Now sum of three vector and it's normal is given as

Cross product of two identical vectors is Zero.
