| Question | Answer |
|---|---|
| What is a three dimensional figure? | A figure with length, width, and height |
| What is volume? | The amount of space inside a figure |
| What is volume measured in? | Cubic units |
| What are ways to find the volume of a rectangular prism? | To count the indivual unit cubes or multiplying it's length, width, and height together to get the total volume |
| What is the volume formula? | V=lwh |
| What figures can be deconstructed into a net? | Prisms and pyramids |
| What is surface area measured in? | Square units |
| How do you find the surface area of prisms and pyramids? | By finding the area of each lateral face |
| What is the formula for a triangle? | a=lw/2 |
| What is the formula for a trapezoid? | a=h(b1+b2)/2 |
| What is the formula for a square/rectangle? | a=lw |
| What are cubic units? | Used to measure volume. Tells the number of cubes of a given size it will take to fill a three dimensional figure |
| What is a lateral face? | Any face that is not a base. |
| What is a net? | A two dimensional figure that can be used to build a three dimensional figure |
| What is a prism? | A three dimensional figure with at least three rectangular lateral faces and top and bottom faces parallel. |
| What is a pyramid? | A three dimensional figure with atleast three triangular sides tbaf meet at a common vertex and only one base that is a polygon |
| What is a rectangular prism? | A prism that has rectangular bases. |
| What is the slant height? | The height of each lateral face of a pyramid |
