Why This Matters Missed a lesson — or just want a refresher? This catch-up station reviews Lessons 5.5 · 5.6 · 5.10: 5.5 Determine the Volume of Rectangular Prisms, 5.6 Represent Three-Dimensional Figures in Two Dimensions, 5.10 Volume of Rectangular Prisms. Work one example from each lesson, then prove you're caught up in the mixed practice.

Start hereWords for this lesson

Read each word before you begin. Say it out loud.

WordWhat it meansExample
VolumeSpanish: Volumen How much space is inside a solid shape. A box 3 × 2 × 4 holds 24 unit cubes, so V = 24 cubic units
Rectangular prismSpanish: Prisma rectangular A solid box shape with six flat rectangle sides. A cereal box or shoe box — it has length, width, and height
Cubic unitsSpanish: Unidades cúbicas The units used to measure space inside, like cubic inches. A tiny cube that is 1 in × 1 in × 1 in = 1 in³ (one cubic inch)
Length, width, heightSpanish: Largo, ancho, altura How long, how wide, and how tall a box is. V = l × w × h: for a box 5 × 3 × 2, volume = 30 cubic units
NetSpanish: Plantilla (desarrollo plano) A flat shape that folds up into a solid. unfolded box
EdgeSpanish: Arista The line where two flat sides of a solid meet. A cube has 12 edges — 4 along the top, 4 along the bottom, 4 vertical

How it worksWorked example

These numbers are not on your problems. The steps are. Follow them with your own numbers.

Net for a box 5 cm × 3 cm × 2 cm.

  1. Bottom and top: 5 cm by 3 cm.
  2. Front and back: 5 cm by 2 cm.
  3. Two sides: 3 cm by 2 cm.

Answer: 6 rectangles, 3 matching pairs

Now you trySame steps, your turn

The steps are the same as the worked example. The numbers are yours. Do the work.

A box is 3 in long, 2 in wide, and 4 in tall. Find its volume.

Watch out!A common mistake

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
