This sugar cube box is a perfect cube and its volume is 1728 cubic centimeters. Each sugar cube inside the box is 2cm x 2cm x 2cm. How many sugar cubes fit along the length of the box?
V=n3
1728=n3
cube root of 1728 = 12
12 cm length / 2 cm cube = 6 cubes
The weight of the blue whale is how many times as great as the weight of the giraffe?
Giraffe: 4 x 104 pounds
Blue Whale: 4 x 107 pounds
1 x 103 = 1,000 times greater
Calculate the difference.
62 liters - 3.4x103 mL
3.4x103 = 3400mL
3400mL = 3.4 liters
62 liters - 3.4 liters = 58.6 liters = 5.86x101 liters

Quantity A is how many times as great as Quantity B?
Quantity A: 4x106
Quantity B: 2x103
2x103=2000 times as great
c) Leonte wants to figure out how many protons make up Mars. Write the mass of a proton in kilograms in order to compare them.
mass of a proton / 1000
1.67x10-24 / 1000
1.67x10-27 kilograms
d) How many protons make up Mars?
mass of Mars / mass of proton =
6.4x1023 kg / 1.67x10-27
3.8x1050 protons make up Mars.
