The correct reported volume of the cardboard needs to be determined. Concept introduction: The volume of the rectangle can be calculated as follows: V = l × b × h Here, l is length, b is breadth and h is height of the rectangle. Rules for rounding off numbers are as follows: If the number to be rounded off is followed by digit 5 or greater than 5, the number will be rounded up. For example: Rounding off number 38, the number is followed by digit 8 which is greater than 5 thus; the number will be rounded up to the nearest ten that is 40. If the number to be rounded off is followed by digit zero or less than 5, the number will be rounded down. For example: Rounding off number 33, the number is followed by digit 3 which is less than 5 thus; the number will be rounded down to the nearest ten that is 30.

The correct reported volume of the cardboard needs to be determined.
Concept introduction:
The volume of the rectangle can be calculated as follows:
V=l×b×h
Here, l is length, b is breadth and h is height of the rectangle.
Rules for rounding off numbers are as follows:
If the number to be rounded off is followed by digit 5 or greater than 5, the number will be rounded up.
For example: Rounding off number 38, the number is followed by digit 8 which is greater than 5 thus; the number will be rounded up to the nearest ten that is 40.
If the number to be rounded off is followed by digit zero or less than 5, the number will be rounded down.
For example: Rounding off number 33, the number is followed by digit 3 which is less than 5 thus; the number will be rounded down to the nearest ten that is 30.
Suppose the metallic paper clips (which contain iron) had been replaced by magnesium or nickel. Would using a magnet as a method of separation have worked?
If that same 225-g sample of water was frozen, what volume would it occupy, given that the density of ice at 273K is 0.9167 g/mL?
A cylindrical glass tube 12.7 cm in length is filled withmercury (density = 13.6 g/mL). The mass of mercuryneeded to fill the tube is 105.5 g. Calculate the innerdiameter of the tube (volume of a cylinder of radius rand length h is V = πr2h).
