When is the length of an object measured to the nearest half inch a whole number?
When you are rounding out to the nearest inch. * * * * * Very funny! If the length is between (x-0.25) inches and (x+0.25) inches it will be rounded to x inches.
Can an object that when measured to the nearest quarter inch have a different length then when measured to the nearest half inch?
Yes, of course, you lose more precision if you round to a half inch. Try rounding 0.76 to the nearest half unit, and to the nearest quarter unit, and see what happens.
Using a metric ruler student x measured the length of an object to the nearest tenth while student y measure the length to the nearest centimeter which measurement is more accurate?
There are 100 centimeters in a meter. The second student (y) would be more accurate.
The perimeter is 45 inches and the width is 15 inches what is the length?
length=7.5 inches this is only correct if the object is a rectangle.
What is the volume of a square pyramid measured in?
The volume of any object is measured in cubic units of length - whatever the shape of the object. The only thing that might change are the units of length themselves: if you are imperial minded, then the volume of a model pyramid would be measured in cubic inches, that of the Egyptian or Central/South American ones would be in cubic yards. If you are SI minded, then you will prefer cubic centimetres or cubic metres.
