The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
2lw x 2wh + 2lh |
|
h2 x l2 x w2 |
|
h x l x w |
|
lw x wh + lh |
A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.
A trapezoid is a quadrilateral with one set of __________ sides.
parallel |
|
equal angle |
|
equal length |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
Which of the following statements about a triangle is not true?
sum of interior angles = 180° |
|
perimeter = sum of side lengths |
|
area = ½bh |
|
exterior angle = sum of two adjacent interior angles |
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.
The dimensions of this trapezoid are a = 5, b = 8, c = 7, d = 6, and h = 3. What is the area?

The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(8 + 6)(3)
a = ½(14)(3)
a = ½(42) = \( \frac{42}{2} \)
a = 21
If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
intersects |
|
midpoints |
|
bisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
