Answer:

Step-by-step explanation:
we know that
<em>Joey can paint a room in 2 hours</em>
That means
Joey can paint the 100% of the room-------> 2 hours
so
In 1 hour ------> can paint 100%/2=50%
<em>Chelsea can paint a room in 3 hours</em>
That means
C<em>helsea</em> can paint the 100% of the room-------> 3 hours
so
In 1 hour ------> can paint (100%/3)=33.33%
therefore
Joey and Chelsea in 1 hour can paint -----> 50%+33.33%=83.33%
by proportion

6. V = 138.125. Just multiply all the numbers together for this problem.
7. SA = 392. Use the formula <span>2(lw + lh + wh). </span>
