36 the height of a 30-story building is approximately
(1) 10^0 m (3) 10^2 m
(2) 10^1 m (4) 10^3 m

An approximation used to measure building height is 10 feet per building level.

Converting from feet to meters using the equation:
1 ft = 0.3048m
10 ft = 3.048m

Multiplying that by 30 storeys, we get:
3 x 3.048m = 91.44m, which is near the answer of (3) 10^2 m or 100m.
