Uncle ben has 440 chickens on his farm. 39 are roosters and the rest are hens. 15 of his hens do not lay eggs. the rest lay eggs. how many egg laying hens does uncle ben have on his farm? (need to use cubes method)

the answer is 26

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

i dont get the question
