| Formulas | ||
| #1 | What is the formula for area of a triangle? |
Area = base x height / 2 |
| #2 | What is the formula for area of a parallelogram?
|
Area = base x height |
| #3 | What formula would you use to find the base of a rectangular pyramid?
|
Area = base x height (because the base is a rectangle) |
| #4 | What formula would you use to find the base (and top) of a triangluar prism?
|
Area = base x height / 2 (because the base and its parallel top are triangles) |
| #5 | What is the formula for surface area of a rectangular prism?
|
Surface area = 2(lw) + 2(lh) + 2(wh) |

| #3 | What is the surface area of the triangular prism below?
|
96 square cm (the rectangles each have areas of 28, 21, and 35 and each triangle has an area of 6) |
| #4 | Find the surface area of the cube below if each side has a length of 3 inches.
|
54 square inches (each face has an area of 9 and there are 6 faces) |
| #5 | If the square area of a cube is 150 square inches, what is the length of each side? |
5 inches (because each face would have an area of 25 square inches and there are 6 faces) |
