a directed line segment AB on the coordinate plane starts from A (-1,3), and ends at B(-10,-10). Find the x-coordinate of point C on line segment AB that partitions the segment into a 5:6 ratio

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
