The dimensions of this cube are height (h) = 5, length (l) = 8, and width (w) = 7. What is the volume?
| 280 | |
| 30 | |
| 5 | |
| 180 |
The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 8 x 7
v = 280
If a = c = 1, b = d = 2, what is the area of this rectangle?
| 6 | |
| 24 | |
| 2 | |
| 63 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 1 x 2
a = 2
What is 8a3 + 2a3?
| 10 | |
| 10a6 | |
| 10a3 | |
| 16a3 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
8a3 + 2a3 = 10a3
