Answer:

Step-by-step explanation:
We have the problem:

6 2/3 can be written as (6 + 2/3), and 3 1/5 can be written as (3 + 1/5). So, we can then use the distributive property:

Now, we need to combine the fractions by finding a common denominator. Here, the common denominator is 3 * 5 = 15: 
Finally, we add 18 to 1 11/15: 
Thus, the answer is
.

Answer:
256√3 in^2.
Step-by-step explanation:
tan 60 = lateral height of 1 face / 8
