The coordinates of triangle DEF are D(-1,4), E(7,-3), and F(9,5). Write a rule for the translation of triangle DEF to triangle D’E’F’, so that the centroid of triangle D’E’F’ is (6,-2).

45 is the only number in both sets

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 !
