The volume of the triangular prism is 54 cubic units. A triangular prism with a volume of 54 cubic units is shown. The triangle has a base length of 4 and a height of x. The height of the prism is 3 x.

What is the value of x?

3
5
7
9

9

Step-by-step explanation:

volume of prism is area of the end times the length.

area of a right trangle is 1/2 base times height.

so 1/2 * 2 *x

there are two right trangles so that means area is 2x

so 2x times length of 3x is 6x

we know overall volume is 54 so

6x=54

x=9

The answer is 3
