To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
lw x wh + lh |
|
2lw x 2wh + 2lh |
|
h x l x w |
|
h2 x l2 x w2 |
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.
The dimensions of this trapezoid are a = 5, b = 6, c = 7, d = 3, and h = 4. What is the area?
| 22\(\frac{1}{2}\) | |
| 28 | |
| 18 | |
| 30 |
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(6 + 3)(4)
a = ½(9)(4)
a = ½(36) = \( \frac{36}{2} \)
a = 18
If a = 2, b = 1, c = 4, and d = 3, what is the perimeter of this quadrilateral?
| 17 | |
| 12 | |
| 29 | |
| 10 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 2 + 1 + 4 + 3
p = 10
The dimensions of this cube are height (h) = 7, length (l) = 6, and width (w) = 2. What is the surface area?
| 92 | |
| 348 | |
| 236 | |
| 136 |
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 6 x 2) + (2 x 2 x 7) + (2 x 6 x 7)
sa = (24) + (28) + (84)
sa = 136
