The dimensions of this cube are height (h) = 2, length (l) = 9, and width (w) = 3. What is the volume?
| 192 | |
| 54 | |
| 126 | |
| 8 |
The volume of a cube is height x length x width:
v = h x l x w
v = 2 x 9 x 3
v = 54
A right angle measures:
360° |
|
90° |
|
45° |
|
180° |
A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.

| 9π | |
| 30π | |
| 19π | |
| 38π |
The formula for circumference is circle diameter x π:
c = πd
c = 19π
If a = c = 5, b = d = 3, what is the area of this rectangle?
| 15 | |
| 32 | |
| 18 | |
| 4 |
The area of a rectangle is equal to its length x width:
