Ro's company ships t-shirts in boxes shaped like cubes. the picture below shows the cube
and its net, raj is designing labels for all of the faces of the boxes. what is the surface area
of each box that rajneeds to cover with labels?

CL.1.142):

A):      

x5 ==>      4 boxes  =   3ft   < x5

20 boxes   =       ?  ft

20 boxes  is    15 ft. high

B):   x3  ===>   4 boxes     =    3ft.  < x3

   ?   boxes           =          9ft.

       12 boxes  will fit in one stack.

c):  CL.143

 Perimeter  =     15  +  29  +  9  +  11  +  6  +  18   >  88m

A1    =    b  *   h

(18)(15)  

270m^2

A2    =   b  *  h

(11)(9)

99

Total  Area >   270    +    99   >  369m^2

CL.1-144

1/4    +   1/4   +   1/5     =    5/20    +   5/20   +   4/20    >    14/20

1/4  *    5/5  >  5/20

1/5   *    4/4    >  4/20

14/20      +      ?/20       =      20/20

?      =       6  Missing    Section

6/20      >     3/10

CL-1.145

A):   40/100       =     4/10   >   2/5

0.4            >    40%

B):    1/6  >   .00000

0.16 (Repeating 6)  >  16.6%

C):   37.5/100     =    375/1000     >     3/8

0.375      >   37.5%

CL-1.146

ADD:   1/6   +   1/2   show all steps:

1/6   +   1/2

1/6    +    3/6

1   +   3 / 6

4/6  >    2/3     >   Decimal:   >   0.666667

Hope that helps                                   : )
