Solve for x
6(x - 1) = 9(x + 2)
O x= -8
O x= -3
0 x = 3
0 x = 8

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 !
