Hello!
To find the area of a rectangular prism you do 2(lw + lh + wh)
Put in the values
2(9 * 2 + 9 * 6 + 2 * 6)
2(18 + 54 + 12)
2(84)
2 * 84 = 168
The answer is 168 cubic inches
Hope this helps!
180 degrees in a triangle. subtract the 2 know angles to get the third.
180-39-24=117
The answer is 60 because
40-10*2=60
hope it helps
