Squared and Cubed Unit Conversion Flashcards

Question 1

If 1 m = 100 cm, what is the matching square-unit equality?

Accepted Answer

1 m² = 10,000 cm². Square the length factor: (100 cm)² = 10,000 cm².

Question 2

Accepted Answer

1 cm³ = 1,000 mm³. Cube the length factor: (10 mm)³ = 1,000 mm³.

Question 3

In 13 cm², what does the exponent apply to?

Accepted Answer

Question 4

Which unit factor converts cm² to m² from 1 m = 100 cm?

Accepted Answer

(1 m / 100 cm)². The cm² in the denominator cancels the starting cm².

Question 5

Which unit factor converts m³ to cm³ from 1 m = 100 cm?

Accepted Answer

(100 cm / 1 m)³. The m³ in the denominator cancels the starting m³.

Question 6

Does 1 L = 1,000 cm³ need another cube to convert liters to cm³?
