To answer this question you will first need to find the value of x, the height of the triangular base.
1. To do this you will use the Pythagorean theorem. Please see the attached picture for the work.
The length of x is 18 units.
Now that we know the length of X, we can use the volume formula to solve for y, the lateral height of the prism.
2. See the attached work for the solution to y.
y = 3 1/3 units
3. The product of 18 and 3 1/3 is. 18 x 3 1/3= 60, letter D.
