What is the volume of this pyramid? 945 cm³ 1260 cm³ 1890 cm³ 2520 cm³ A pyramid with a right triangular base. The right triangular base has a base length of fourteen centimeters and a height of eighteen centimeters. The height of the pyramid is thirty centimeters long.

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
