Question

A triangular pryamid is shown in the diagram. What is the volume of the triangular pyramid?

Answer 1

Given the following question:

`\begin{gathered} V=(1)/(3)BH \\ B=\text{ Base Area} \\ A=(1)/(2)BH \\ B=7.8 \\ H=4 \\ A=(1)/(2)7.8(4) \\ 7.8*4=31.2 \\ 31.2/2=15.6 \\ A=15.6 \\ V=(1)/(3)BH \\ B=15.6 \\ H=4 \\ (1)/(3)15.6(4) \\ 15.6(4)=62.4 \\ 62.4/3=20.8 \\ V=20.8 \end{gathered}`

Volume is equal to 20.8 cubic centimeters.
