Question

what is the volume of a right triangular pyramid whose base is 5 meters on each side and whose altitude is 4 meters? round to the nearest hundred

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

Right triangular pyramid

base = 5 meters

altitude = 4 meters

Volume = ?

Step 02:

The volume of a right triangular pyramid

V = 1/3 B * h

B = 1/2 b * h

`\begin{gathered} B\text{ = }(1)/(2)\cdot5m\cdot4m \\ B=\text{ }10m^2 \end{gathered}`
`V\text{ = }(1)/(3)\cdot10m^2\cdot4m=\text{ }13.3333m^3`

The answer is:

The volume of the pyramid is 13.33 m³.
