Bob has 4,000 grams of sand. If his brother has one kilogram more than Bob, how many kilograms of sand does Bob's brother have?

Step-by-step explanation:

5 kg

Step-by-step explanation:

1 kg = 1000 g

4 kg = 4000 g

? kg = 5000 g

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

17 1/3
