Understanding the Bb.1 Idea
The Fundamentals of Bb.1
Bb.1 is an IXL Math seventh Grade talent that focuses on discovering the quantity of prisms and cylinders. A prism is a three-dimensional form with two parallel faces referred to as bases, and the remaining faces are parallelograms. In a cylinder, the bases are circles, and the remaining faces are rectangles. The quantity of a strong is the quantity of house it occupies in three dimensions.
Discovering the Quantity of Prisms and Cylinders
The method for the quantity of a prism is:
Quantity = base space × top
For a cylinder, the method is:
Quantity = base space × top
The bottom space of a prism is the realm of one of many bases, and the peak is the space between the bases. For a cylinder, the bottom space is the realm of the circle, and the peak is the space between the 2 bases.
Instance
Discover the quantity of an oblong prism with size 5 cm, width 3 cm, and top 2 cm.
Step 1: Discover the bottom space.
Base space = size × width = 5 cm × 3 cm = 15 cm²

Top = 2 cm
Step 3: Discover the quantity.
Quantity = base space × top = 15 cm² × 2 cm = 30 cm³
| Form | Components |
|---|---|
| Rectangular prism | Quantity = size × width × top |
| Triangular prism | Quantity = (1/2 × base × top) × top |
| Cylinder | Quantity = π × radius² × top |
