A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
If side x = 12cm, side y = 11cm, and side z = 8cm what is the perimeter of this triangle?
| 28cm | |
| 27cm | |
| 31cm | |
| 32cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 12cm + 11cm + 8cm = 31cm
The dimensions of this cube are height (h) = 3, length (l) = 1, and width (w) = 5. What is the volume?
| 216 | |
| 60 | |
| 15 | |
| 140 |
The volume of a cube is height x length x width:
v = h x l x w
v = 3 x 1 x 5
v = 15
The dimensions of this cylinder are height (h) = 4 and radius (r) = 7. What is the volume?
| 72π | |

| 1π | |
| 196π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(72 x 4)
v = 196π
