Volume of Rectangular Prisms · Volume
- Convert mixed numbers to improper fractions before multiplying
- Multiply numerators across, multiply denominators across: V = (l · w · h)
- Simplify the fraction and label with cubic units
- Volume of Rectangular Prisms (Volumen de prismas rectangulares) — The space inside a rectangular prism. Formula: V = Bh = 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.
- Dimensions (Dimensiones) — How long, how wide, and how tall a shape is.
- Base area (Área de la base) — The area of the bottom of a solid. Volume = base area × height.
- A common mistake in Volume of Rectangular Prisms is rounding a fractional edge length to the nearest whole number before multiplying, instead of using the exact fraction or decimal. For a box that is 2 ft × 1.5 ft × 1 ft, a student might round 1.5 down to 1 and compute 2 × 1 × 1 = 2 ft³, but the correct volume uses the exact edge length: 2 × 1.5 × 1 = 3 ft³ — a full cubic foot larger. Before you submit, ask: 'Did I multiply using the exact fractional or decimal edge length, or did I round it off first?'
