The dimensions of this cube are height (h) = 6, length (l) = 7, and width (w) = 5. What is the surface area?
| 214 | |
| 152 | |
| 198 | |
| 352 |
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 5) + (2 x 5 x 6) + (2 x 7 x 6)
sa = (70) + (60) + (84)
sa = 214

Which of the following is not a part of PEMDAS, the acronym for math order of operations?
addition |
|
exponents |
|
pairs |
|
division |
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.)
If a = c = 6, b = d = 3, what is the area of this rectangle?
| 18 | |
| 25 | |
| 54 | |
| 40 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 6 x 3
a = 18
