The edge of a cube is a = 1.2 × 10 -2 m. Then its volume will be recorded as:
Text Solution
Verified by ExpertsThe correct answer is:
C
V = λ 3 = (1.2 × 10 –2 m) 3 = 1.728 × 10 –6 m –3
length ( λ ) has two significant figure, the volume (V) will also have two significance figures. Therefore, the correct answer is
V = 1.7 × 10 -6 m 3
