Answer:
144
Step-by-step explanation:
First, do the top and bottom. The top is 2*4*3 or 24, and the bottom is 6*4 or 24.
Now, do the sides. It is a staircase that you can split into 6 2x2 blocks, or 6*4=24. Do the same with the other side to get 24 again.
Now for the front and back. This is 2*4*3 and 6*4 again, or 24 and 24.
Now you have 6 24's so just multiply these and get 144.

I say the second one but I could be wrong..
Answer:
JK = 13
Step-by-step explanation:
Note that corresponding sides are congruent.
Thus ST = KL and JK = RS
Given ST = 16RS and KL = 13JK + 39, thus
KL = 13JK + 39 ( KL = ST = 16RS ), substituting
16RS = 13RS + 39 ( JK = RS )
Subtract 13RS from both sides
3RS = 39 ( divide both sides by 3 )
RS = 13
However, RS and JK are corresponding sides and congruent, thus
JK = RS = 13
