Question

Find the volume of the given solid. under the surface z = 5xy and above the triangle with vertices (1, 1), (4, 1), and (1, 2)

Answer 1

So right now you see that you have x and y intercept right? Then plug those intercepts in equation that you have and solve for z. Which means z=5(1)(1) will be 5, 5(4)(1) will be 20, and 5(1)(2) will be 10. So, overall you have 5, 20, 10.
