Knowing that an optimal shape is a cube is critical to solving this problem. With you now having that in mind, each side of the cube has a length of 4 inches. So the area of 1 face is 16 square units and the total surface area is 96 square units.
Answer:
600 x 60 = 36,000
50 x 50 = 2,500
1,000 x 3 = 3,000
70 x 80 = 5,600
100 x 300 = 30,000
20 x 40 = 800
90 x 90 = 8,100
9 x 900 = 8,100
500 x 300 = 150,000
1,000 x 5 = 5,000
125 - 100
770 - 800
364 - 400
923 - 900
755 - 800

Answer:
10 years old
Step-by-step explanation:
Let's say the age of the younger sister is x. Then the age of the older sister must be x + 2 because the ages are consecutive <em>even</em> numbers.
"Twice the age of the youngest exceeds the oldest by 8" means that we multiply x by 2 and set that equal to (x + 2) + 8:
2x = (x + 2) + 8
2x = x + 10
x = 10
So, the youngest sister is 10 years old.
