The width, length, and height of a large, custom-made shipping crate are 1.12 m, 1.25 m, and 0.83 m, respectively. The volume of
the box using the correct number of significant figures is ________ m3. The width, length, and height of a large, custom-made shipping crate are 1.12 m, 1.25 m, and 0.83 m, respectively. The volume of the box using the correct number of significant figures is ________ m3. 1.16 1.2 1.1620 1.162 1.16200
In the product of two or more physical quantities , the number of places after decimal in the result can never be more than least number of place after decimal in the quantities that are being multiplied .
Here numbers that are being multiplied are ,
1.12 , 1.25, and .83 , each containing two digits after decimal . So the product can not contain more than two digits after decimal . The principle behind it is that the result can not have more precision than the precision of amount that are being multiplied.
so
1.12 x 1.25 x .83 = 1.162 to be rounded off to 1.16 .
