The answer is 48. You find the volume of the box - 12 X 8 X 4 = 384 Find the volume of the Cube with side 2 cm - 2 X 2 X 2 = 8 344 divided by 8 = 48 Therefore, 48 cubes would fit into the box
So 100% - 20% - 10% - 30% = 40% 40% of people were men. It says that there were 3600 men and in order to find the total amount of people, do 3600/40% or 3600/.4 Which equals 9000
A given angle measures 90°.. Then, note that the total measurement of the triangle is 180°... Subtract 180° by 90°, and the other angles must add up to 90°!
