Study Notes

Rectangular Prisms

  • A rectangular prism is a three-dimensional shape with two identical, parallel, and regular rectangles connected by four rectangles.
  • The cross-section of a rectangular prism is the same regardless of where it is cut.

Characteristics of Rectangular Prisms

  • Consist of two identical rectangles on either end, connected by four additional rectangles.
  • Volume is the measure of the inside of a rectangular prism.

Formula for Volume of a Rectangular Prism

  • The formula is V = L × W × H, where V is the volume, L is the length, W is the width, and H is the height.
  • The formula yields a product with a cubed measure (e.g., inches cubed, in³).

Measuring Volume

  • The three important measures of a rectangular prism are length, width, and height.
  • These measures are multiplied together to get a cubed volume for the prism.

Applications of Rectangular Prisms

  • Volume is an important measure for understanding how much can fit inside a rectangular prism.
  • Examples of rectangular prisms include packing boxes, shipping containers, and mail services use volume to determine shipping fees.

Examples of Finding Volume

  • Example One: Find the volume of a rectangular prism with fractions (L = 2, W = 4.5, H = 3.5) → V = 31.5 units cubed.
  • Example Two: Find the volume of a rectangular prism with mismatched units (L = 42 in, W = 38 in, H = 5 ft) → V = 95,760 in³.
  • Example Three: Find the width and volume of a rectangular prism with dependent measures (L = 5 in, W = 1/3 H, H = 6 in) → Width = 2 in, V = 60 in³.
