\begin{gathered} V=330cm^3 \\ \text{DBB = 11 cm} \\ A_{B\text{ }}=30cm^2 \end{gathered}

Here, we want to calculate the volume of the triangular prism

Mathematically, to calculate this, we have to multiply the area of the base by the height of the prism

The base of the prism is the right triangle

The height is the DBB which we have as 11 cm

The area of the base is the area of the right triangle calculated as follows;


A_B\text{ = }(1)/(2)* B* H\text{ = }(1)/(2)*12*5=30cm^2

So, we have the volume as;


30cm^2\text{ }*11\text{ cm = 330 }cm^3
