Well, notice the composite is really just 4 triangles atop sitting on top of 4 rectangles, and all of them area stacked up at the edges.
so, for the rectangle's sides,
front and back are two 6x3 rectangles
left and right are two 6x3 rectangles
the bottom part is a 6x6 rectangle
now, we don't include the 6x6 rectangle that's touching the triangles, because that's inside area, and is not SURFACE area, so we nevermind that one.
now, the triangles are just four triangles with a base of 6, and a height of 4, in red noted there.
so, just get the area of all those rectangles and the triangles, sum them up and that's the surface area of the composite,

Answer:
t = 5 seconds
Step-by-step explanation:
A golfer takes a swing from a hill twenty feet above the cup with an initial upwards velocity of 76 feet per second.
We need to find how long does it take the ball to land on the ground near the cup.
The equation for the path of the ball is given using second equation of kinematics as follows :
Neglecting negative value,
It will take 5 seconds for the ball to land on the ground near the cup.
