2. What is a prism?
A prism is a solid with a uniform cross-section. This means it has the same shape for all of its length.
e.g. A shoe box is usually a prism. Its cross-section is a rectangle.
3. How is the volume of a prism calculated?
Find the area of the cross-section and multiply the answer by its length.
4. What is the difference between a rhombus and a parellogram?
Both have pairs of parallel sides but a rhombus has all of its sides of equal length.
