Quinn has 6 bottles of water that each weighs 3/5 pound. What is the total weight of the water bottles?

Step-by-step explanation:

6b(3lb/5b)=3.6lb

3rd box is the answer

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
