Modeling Structures with Scale and Proportions

The video tutorial explains the concept of scale as a ratio between two sets of measurements. It provides examples of scaling models, such as the CN Tower, a T-Rex, and the Leaning Tower of Pisa, using blocks. The tutorial demonstrates how to calculate the number of blocks needed for each model by using proportions and equivalent fractions.

What is the primary purpose of using scale in drawings and models?

• To make objects appear larger

• To increase the accuracy of measurements

• To reduce the complexity of designs

• To fit large objects onto smaller surfaces

If a map scale is 1 inch equals 40 miles, what does this imply?

• 40 inches on the map represent 1 mile in reality

• 40 miles on the map represent 1 inch in reality

• 1 inch on the map represents 40 miles in reality

• 1 mile on the map represents 40 inches in reality

How many blocks are needed to build a model of the CN Tower if each block represents 100 feet?

• 18 blocks

• 36 blocks

• 180 blocks

• 1,800 blocks

What would be a more practical scale for building a model of the CN Tower using blocks?

• 1 block equals 10 feet

• 1 block equals 1,000 feet

• 1 block equals 50 feet

• 1 block equals 1 foot

If one block equals 50 cm, how many blocks are needed for a 6-meter tall T-Rex model?

• 60 blocks

• 12 blocks

• 120 blocks

• 6 blocks

How do you convert meters to centimeters?

• Divide by 100

• Divide by 10

• Multiply by 100

• Multiply by 10

What is the scale used for the Leaning Tower of Pisa model?

• 2 blocks equal 15 feet

• 15 blocks equal 2 feet

• 15 blocks equal 1 foot

• 1 block equals 15 feet

How many blocks are needed to replicate the Leaning Tower of Pisa if it is 180 feet tall?

• 12 blocks

• 18 blocks

• 24 blocks

• 36 blocks

What mathematical method can be used to solve proportions in scaling problems?

• Division

• Addition

• Subtraction

• Cross-multiplication

Why is it important to choose an appropriate scale when building models?

• To accurately represent the original structure

• To ensure the model is as large as possible

• To minimize the number of materials used

• To make the model more visually appealing
