The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 3 x 2
v = 30
The dimensions of this cylinder are height (h) = 1 and radius (r) = 2. What is the surface area?
| 132π | |
| 156π | |
| 12π | |
| 256π |
The surface area of a cylinder is 2πr2 + 2πrh:
sa = 2πr2 + 2πrh
sa = 2π(22) + 2π(2 x 1)
sa = 2π(4) + 2π(2)
sa = (2 x 4)π + (2 x 2)π
sa = 8π + 4π
sa = 12π
The dimensions of this cube are height (h) = 2, length (l) = 1, and width (w) = 8. What is the surface area?
| 190 | |
| 210 | |
| 52 | |

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 1 x 8) + (2 x 8 x 2) + (2 x 1 x 2)
sa = (16) + (32) + (4)
sa = 52
The dimensions of this cylinder are height (h) = 3 and radius (r) = 6. What is the volume?
| 288π | |
| 8π | |
| 108π | |
| 75π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(62 x 3)
v = 108π
The dimensions of this cube are height (h) = 5, length (l) = 3, and width (w) = 2. What is the volume?
