Question

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 1

Option 2. Volume = 1260 cm³

Explanation:

As we know the formula of volume of a right angle triangle

`V=(1)/(3)* (A){h}`

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

`A=(1)/(2)h'* b`

`A=(1)/(2)* 14* 18=7* 18=126cm^(2)`

`V=(1)/(3)* 30* 126`

Therefore Volume of the pyramid = 1260 cm³
