are given by 1 = 12 cm, b = 6 cm and t = 2.45
cm. the volume of the block according to the
idea of significant figures should be:​

Answer 1

Answer:

volume = lbh

=12 x 6 x 2.45

= 176.4cm^3

Answer 2

Question :-

❥ The length, breadth and thickness of a block are given by l=12 cm, b=6 cm and t=2.45 cm. The volume of the block according to the idea of significant figure should be :-

Answer :-

⇒ The volume will contain only 1 significant figure .

Given :-

❥ length of a block ↠ 12cm.

❥ Breadth of a block ↠ 6cm.

❥ thickness of a block ↠ 2.45cm.

{To find:-}

❥ The volume of the block according to the idea of significant figure should be :-

❥ As we know that ,

Volume of block = l × b × t

$Now$,

✒ length ( l ) ↠ 12cm.

✒ Breadth ( b ) ↠ 6cm.

✒ thickness ( t ) ↠ 2.45cm.

Now ,

✒ putting the values in the above formula

we get ,

⇒ Volume of a block  ↠ 12 × 6 × 2.45

⇒   Volume of a block  ↠ 176.4 cm³

⇒ Volume of a block ↠ 176.4 × ( 10²/10² ) cm³

⇒  Volume of a block ↠ 1.764 × 10² cm³

⇒ Volume of a block ↠ 2 × 10² cm³        

The minimum number of significant figure is 1.

so, the volume will contain only 1 significant figure .
