The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
h2 x l2 x w2 |
|
h x l x w |
|
lw x wh + lh |
|
2lw x 2wh + 2lh |
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.
Which of the following is not required to define the slope-intercept equation for a line?
y-intercept |
|
x-intercept |
|
slope |
|
\({\Delta y \over \Delta x}\) |
A line on the coordinate grid can be defined by a slope-intercept equation: y = mx + b. For a given value of x, the value of y can be determined given the slope (m) and y-intercept (b) of the line. The slope of a line is change in y over change in x, \({\Delta y \over \Delta x}\), and the y-intercept is the y-coordinate where the line crosses the vertical y-axis.
Which of the following statements about a parallelogram is not true?
the area of a parallelogram is base x height |
|
opposite sides and adjacent angles are equal |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
a parallelogram is a quadrilateral |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
The dimensions of this cube are height (h) = 6, length (l) = 7, and width (w) = 1. What is the volume?
| 12 | |
| 28 | |
| 42 | |
| 40 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 7 x 1
v = 42
If a = c = 8, b = d = 9, what is the area of this rectangle?
| 72 | |
| 12 | |
| 2 | |
| 5 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 8 x 9
a = 72
