Question

Here is a triangular prism.

Area = (b.h)/2
The triangular prism is 3cm 5cm 11cm and 4 cm
what is the suface area of the prism

Answer 1

To find the volume of the triangular prism use the following formula:

`V=B\cdot h`

Where B is the triangular base and h is the height of the prism.

Find the area of the triangular base by using the following formula:

`\begin{gathered} A=(b\cdot h)/(2) \\ A=(6in\cdot10in)/(2) \\ A=(60in^2)/(2) \\ A=30in^2 \end{gathered}`

Now, find the volume of the triangular prism:

`\begin{gathered} V=B\cdot h \\ V=30in^2\cdot15in \\ V=450in^3 \end{gathered}`

It means that the volume of the prism is 450in^3.
