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

1.16 .

Explanation:

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 .

The answer is 1.16.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
