Build it right.Constrúyelo bien.
The Maker Workshop is building crates, foam blocks and clay boxes, and many of the edges are fractions. Find how much space each one holds before the orders go out.
El Taller de Creadores construye cajas, bloques de espuma y cajas de arcilla, y muchas de las aristas son fracciones. Halla cuánto espacio contiene cada una antes de enviar los pedidos.

Wake up what you know, then explore today's model.
Activa lo que sabes y luego explora el modelo de hoy.
- A box has a square base 4 feet by 4 feet and is 1.5 feet tall. Use the model to find the base area. Predict the volume, then multiply. Next, round 1.5 to 1 and to 2 and compare. Explain why rounding the edge gives the wrong volume.

- What is the volume of a rectangular prism with l = 4 in, w = 3 in, h = 5 in?
- 12 in³
- 24 in³
- 60 in³
- 60 in²

- 2 cm
- 3 cm
- 6 cm
- 12 cm
- How is volume different from area?
- Volume uses cubic units; area uses square units
- Volume uses square units; area uses cubic units
- Volume only applies to cubes; area applies to all shapes
- There is no difference

- Fill in the table
- Two boxes: Box A is 10 × 5 × 4 inches. Box B is 8 × 6 × 5 inches. Which has more volume and by how much?
- Box B by 40 in³
- Box A by 40 in³
- Box B by 60 in³
- They're equal
- Spot the Common Mistake
- What is the best next move?
- Add the base and the height: 3 + 2.
- Divide the base area by the height: 3 ÷ 2.
- Write 3 ft² as the volume of the box.
- Multiply the base area by the height: 3 × 2.

- What is the tank's volume?
- 52 in³
- 576 in³
- 4,608 in³
- 4,806 in³
- About how many gallons does the tank hold?
- about 2
- about 20
- about 200
- about 231
- Why divide by 231 instead of multiplying?
- Because dividing always makes numbers smaller
- Because you are finding how many 231-in³ gallons fit inside the tank
- Because 231 is bigger than 24
- Because gallons are bigger than inches
