The dimensions of this cube are height (h) = 2, length (l) = 4, and width (w) = 6. What is the volume?
| 180 | |
| 48 | |
| 81 | |
| 384 |
The volume of a cube is height x length x width:
v = h x l x w
v = 2 x 4 x 6
v = 48

An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
If angle a = 59° and angle b = 24° what is the length of angle c?
| 97° | |
| 68° | |
| 58° | |
| 86° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 59° - 24° = 97°

Which of the following statements about a triangle is not true?
exterior angle = sum of two adjacent interior angles |
|
perimeter = sum of side lengths |
|
sum of interior angles = 180° |

area = ½bh |
A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.
