Question

Anyone knows geometry or what?

Answer 1

378

Explanation:

The base is a right triangle. First, find the area of the triangle.

`A=(1)/(2)(base)(height)`

The base and height always are perpendicular, so use the 9 and the 12.

`A=(1)/(2)(9)(12)`

`A=54`

Now multiple the base area by the height of the overall prism, which is 7

`V=(54)(7)`

`V=378`
