An 8th grade class project involves decorating a rectangular box with the following dimensions. length: 12 inches

width:8 3/4 inches

height:10 1/2 inches

What is the total surface area of this box to the nearest hundredth?

please help lol

i can't see the picture : /

c: lkllmn.

hope it's you

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
