The dimensions of this cube are height (h) = 5, length (l) = 7, and width (w) = 6. What is the surface area?
| 136 | |
| 288 | |
| 106 | |
| 214 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 7 x 6) + (2 x 6 x 5) + (2 x 7 x 5)
sa = (84) + (60) + (70)
sa = 214
A trapezoid is a quadrilateral with one set of __________ sides.
equal length |
|
right angle |
|
equal angle |
|
parallel |
A trapezoid is a quadrilateral with one set of parallel sides.
A coordinate grid is composed of which of the following?
origin |
|
x-axis |
|
all of these |
|
y-axis |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
If a = 8, b = 3, c = 7, and d = 5, what is the perimeter of this quadrilateral?
| 15 | |
| 11 | |
| 18 | |
| 23 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 8 + 3 + 7 + 5
p = 23
Which of the following is not a part of PEMDAS, the acronym for math order of operations?
addition |
|
pairs |
|
division |
|
exponents |
When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
