Well, we know the formula for volume is L*W*H

L=4

W=1/2

H=2

4*1/2*2=4 cm cubed

Please, please give brainliest, it would be greatly appreciated, I only need one more before I advance, thanks!

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

i believe that the slope of the line is -5
