Solution
The correct option is A 0.48 m
Height of step 1: 150 mm = 0.15 m
Height of step 2: 16 cm = 0.16 m
Height of step 3: 0.17 m
Total height = 0.15 m + 0.16 m + 0.17 m = 0.48 m
Height of step 1: 150 mm = 0.15 m
Height of step 2: 16 cm = 0.16 m
Height of step 3: 0.17 m
Total height = 0.15 m + 0.16 m + 0.17 m = 0.48 m
