I need help! please show work!

Answer:
1456 cm square
Step-by-step explanation:
24 x 9 x 2+23 x 16 x 2+16 x 9 x 2=1456
The box have 6 side and 24 x 16 is one side but it have other side is same of 24 x 16 so x2 for 24 x 9 and other is same just make sure all the number is going for 2 time .
But if the number is 24 , 9 , 9 just make sure the 9 is going 4 time
like 9 x 9 x 4 and 24 x 9 x 2 .
24 x 9 x 2=two same side of this box
Answer:
1488
Step-by-step explanation:
take each length and width and multiple them.
9x16=144
9x24=216
16x24=384
now now we ad them up
144+216+384 = 744
and since there is 2 of each side we didn't have to do the rest we just have to multiply what we got by 2.
744 x 2 = 1488.
i hope this made at least a little sense i'm not the best at explaining.
