Volume with Whole-Number Edges · Volume
- Identify the length, width, and height of the box
- Multiply base area (l × w) by height (h)
- Label answer in cubic units (e.g. in³, cm³, ft³)
- Volume with Whole-Number Edges (Volumen con aristas de números enteros) — The number of unit cubes inside a rectangular prism. Formula: V = l × w × h.
- Volume (Volumen) — How much space is inside a solid shape.
- Rectangular prism (Prisma rectangular) — A solid box shape with six flat rectangle sides.
- Cubic units (Unidades cúbicas) — The units used to measure space inside, like cubic inches.
- Length, width, height (Largo, ancho, altura) — How long, how wide, and how tall a box is.
- Net (Plantilla (desarrollo plano)) — A flat shape that folds up into a solid.
- A common mistake in Volume with Whole Number Edges is multiplying only two of the three edges and stopping there — for example, seeing a box that is 6 in long, 4 in wide, and 3 in tall, multiplying just 6 × 4 = 24, and calling that the volume, when 24 is only the area of the bottom face (in square inches), not the volume of the whole box. The height must also be multiplied in: V = 6 × 4 × 3 = 72 cubic inches. A second common mistake is adding the three edges instead of multiplying them (6 + 4 + 3 = 13 instead of 6 × 4 × 3 = 72 cubic inches). Volume always MULTIPLIES all three edges, and the answer is always labeled in cubic units (in³), never square units (in²) or plain units (in).
