The length, breadth and thickness of a block are given by l = 12cm, b = 6 cm and t = 2.45 cm. The volume of the block according to the idea of significant figures should be:
Text Solution
Verified by ExpertsThe correct answer is:
B
V = length × breadth × thickness
= 12 × 6 × 2.45
= 176.4 cm3
= 1.764 × 10 2 cm 3 The minimum number of significant figures is 1 in breadth, hence, the volume will contain only one significant figure,
Therefore, V = 2 × 10
2 cm 3
