First of all, find out the volume of the piece:
V = 12 x 12 x 12
V = 1728 cm3
The density of aluminum is 2.70 g cm-3 therefore all you have to do is:
1728 x 2.7 = 4665.6 grams ---> 4.6656kg.

42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
12 x 5 = 60 That's because 12 x 100 = 600 12/2 = 6
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
