Answer:
360
Step-by-step explanation:
First, find the area of the faces. 6 2/3 x 8 = 20/3 x 8. It then equals 180/3, divided by two, it is 30. But, we have to multiply it by two again because there are two faces. It is now 60.
Now for the bases, 15 x 20/3 = 300/3 = 100x3 = 300
Finally, add 60 and 300 to get 360!
