The Universal Volume Formula for Prisms
The Universal Volume Formula for Prisms is a skill on Pengi from Section 14.4: Volumes of Prisms in Big Ideas Math, Advanced 2.
Key Concepts
Property You don't need a million different formulas for prisms! The volume of ANY prism is simply the area of its base multiplied by its height: $$V = Bh$$ (where B is the area of the base shape, and h is the height of the prism).
Examples Rectangular Prism: A box has a length of 6 in, a width of 3 in, and a height of 4 in. First, find Big B (the area of the rectangle): B = 6 x 3 = 18 sq in. Then, multiply by height: V = 18 x 4 = 72 cubic inches. Triangular Prism: The triangular base has a base of 8 ft and a triangle height of 5 ft. The prism is 10 ft long (prism height). First, find Big B (the area of the triangle): B = 1/2 x 8 x 5 = 20 sq ft. Then, multiply by prism height: V = 20 x 10 = 200 cubic feet.
Explanation Think of calculating volume like building a skyscraper layer by layer! The area of the base (Big B) tells you exactly how many cubic blocks fit perfectly into the very first bottom layer. The height (h) tells you how many layers you need to stack up. So, the number of blocks in one layer multiplied by the number of layers equals your total volume!
