Answer:
Option 2. Volume = 1260 cm³
Step-by-step explanation:
As we know the formula of volume of a right angle triangle
[tex]V=\frac{1}{3}\times (A){h}[/tex]
Here V is the volume of pyramid
A = area of the triangular base
h = height of the triangle
Now we put the values in the formula
[tex]A=\frac{1}{2}h'\times b[/tex]
[tex]A=\frac{1}{2}\times 14\times 18=7\times 18=126cm^{2}[/tex]
[tex]V=\frac{1}{3}\times 30\times 126[/tex]
Therefore Volume of the pyramid = 1260 cm³
