Module 1: The International System of Units (SI)

 

Answers will vary. Sample answers are given.

 

SC 1. My closet is 90 cm wide, 65 cm deep, and 244 cm high.

  1. eqn056.eps

  2. eqn057.eps

  3. The answer makes more sense in cubic metres since the volume of the closet is close to 1.5 m3. I can picture 1.5 more easily than 1 427 400 cm3.

SC 2. The cereal box I measured is 16 cm wide, 2.5 cm deep, and 20 cm high.

  1. eqn058.eps

  2. eqn059.eps

  3. The answer makes more sense in cubic centimetres, as I can picture 800 more easily than 0.0008.

SC 3. 1 m3 = 1 000 000 cm3 or 106 cm3

 

eqn060.eps

 

SC 4. All the dimensions must be in metres.

 

 

 

eqn061.eps

 

eqn062.eps
