Ok so if 1200 total pens and 60 were taken that's a ratio of 1200/60=20
out of 60pens 4 didn't work, again ratio is 4/60=1/15 so about 1/15 of the pens didn't work. 
so we have 1200pens * 1/15broken ratio = 80 pens or we can say 
20*4=80pens won't work from 20 groups of 60 and 4 out of 60 not working is 20*4=80 not working from total batch of 1200.
hope this helps you some! thank you!!!!!!!!!

Answer:
184.8 cubic cm
Step-by-step explanation:
The formula for the volume of a pyramid is 
V = (1/3)(B)(h)      where B is the area of the base, and h is the height
We are given B = 44 cm² andh = 12.6cm  
Plug them into the formula and simplify...(I'm assuming you are allowed to use a calculator for these problems)
V = (1/3)(44cm²)(12.6cm)
<h2>     V = 184.8 cm³  or 184.8 cubic cm</h2><h2 />
