Noice Brainy is good becuase it gives answers out for free but there is a limit sometimes
To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.
The perimeter of any shape is just what you get when you add up all of the side lengths. We know that one side is 462 meters, and since a square has four equal sides, we can just mulitply 462 × 4 to get our perimeter, 1,848 meters.
<span>Are you in K12?? </span>Well Pltw has something to do with k12.....Project Lead The Way provides transformative learning experiences for K-12 students and teachers across the U.S. We create an engaging, hands-on classroom environment........ soooo yea...?
Sorry I don't know anything about that!
Hope this helps somehow, Ayitzdaisy!
