Quiz thématique 2 : Measurement, conversions and scale drawings

  1. Question 1 sur 15

    How many millimetres are in exactly 1 inch?
    Voir la réponse

    Réponse: D. 25.4 mm

    In Canadian law, 1 inch is 1/36 of a yard and 1 yard is 0.9144 m, which makes 1 in exactly 25.4 mm (2.54 cm).

  2. Question 2 sur 15

    A stud is 8 ft long. About how long is it in metres? (1 ft = 0.3048 m)
    Voir la réponse

    Réponse: B. 2.44 m

    Multiply feet by 0.3048: 8 × 0.3048 = 2.4384, about 2.44 m.

  3. Question 3 sur 15

    A steel plate is 3/8 in thick. What is this in millimetres, to one decimal place?
    Voir la réponse

    Réponse: B. 9.5 mm

    3/8 = 0.375 in. 0.375 × 25.4 = 9.525, about 9.5 mm.

  4. Question 4 sur 15

    A door opening is 1,830 mm high. What is this in feet and inches, to the nearest inch?
    Voir la réponse

    Réponse: B. 6 ft 0 in

    1,830 ÷ 25.4 = 72.05 in, about 72 in. 72 ÷ 12 = 6, so it is 6 ft 0 in.

  5. Question 5 sur 15

    About how many square feet are in 1 square metre?
    Voir la réponse

    Réponse: A. 10.76 ft²

    1 m = 3.2808 ft, so 1 m² = 3.2808 × 3.2808 = 10.76 ft². Square the length factor for areas.

  6. Question 6 sur 15

    How many cubic feet are in 1 cubic yard?
    Voir la réponse

    Réponse: D. 27 ft³

    1 yd = 3 ft, so 1 yd³ = 3 × 3 × 3 = 27 ft³. (9 is the number of square feet in a square yard.)

  7. Question 7 sur 15

    About how many cubic metres are in 1 cubic yard? (1 yd = 0.9144 m)
    Voir la réponse

    Réponse: D. 0.76 m³

    Cube the length: 0.9144 × 0.9144 × 0.9144 = 0.7646, about 0.76 m³.

  8. Question 8 sur 15

    A tank holds 20 Canadian (imperial) gallons. How many litres is that, to one decimal place? (1 gallon = 4.54609 L)
    Voir la réponse

    Réponse: C. 90.9 L

    Multiply gallons by 4.54609: 20 × 4.54609 = 90.9 L.

  9. Question 9 sur 15

    A bag of mortar mix weighs 50 lb. What is this in kilograms, to one decimal place? (1 lb = 0.45359237 kg)
    Voir la réponse

    Réponse: D. 22.7 kg

    Multiply pounds by 0.45359237: 50 × 0.4536 = 22.7 kg.

  10. Question 10 sur 15

    A floor plan is drawn at a scale of 1:50. A wall measures 84 mm on the plan. How long is the real wall?
    Voir la réponse

    Réponse: C. 4.2 m

    At 1:50, every unit on the plan is 50 real units: 84 × 50 = 4,200 mm = 4.2 m.

  11. Question 11 sur 15

    A drawing uses the scale 1/4 in = 1 ft. A line on it measures 6 1/2 in. How long is the real object?
    Voir la réponse

    Réponse: C. 26 ft

    Each 1/4 in is 1 ft, so there are 4 ft in every inch: 6.5 × 4 = 26 ft.

  12. Question 12 sur 15

    A beam is 7.5 m long. How long should it be drawn on a 1:100 plan?
    Voir la réponse

    Réponse: B. 75 mm

    7.5 m = 7,500 mm. At 1:100, divide by 100: 7,500 ÷ 100 = 75 mm.

  13. Question 13 sur 15

    You need 15 m of conduit. About how many feet is that, to one decimal place?
    Voir la réponse

    Réponse: D. 49.2 ft

    Divide metres by 0.3048 to get feet: 15 ÷ 0.3048 = 49.2 ft.

  14. Question 14 sur 15

    On a 1:20 detail drawing, a part measures 135 mm. How long is the real part?
    Voir la réponse

    Réponse: B. 2.7 m

    Multiply by the scale: 135 × 20 = 2,700 mm = 2.7 m.

  15. Question 15 sur 15

    A room is 12 ft by 15 ft. What is its floor area in square metres, to one decimal place?
    Voir la réponse

    Réponse: D. 16.7 m²

    Area = 12 × 15 = 180 ft². 1 ft² = 0.3048 × 0.3048 = 0.0929 m², so 180 × 0.0929 = 16.7 m².
