A metric ruler measures in inches and centimeters.
to find the new focal length when the lens is put into water it becomes the 4 times the focal length in air.
Not clear what you mean. 40 millimeters are 4 centimeters.
yes
Moved From Discussion Page - Posted by Aggie Earth doesn't have a 'length.' It has a circumferance, a mass, a volume, even a length of time or age, but it doesn't have a length.
The length of the other diagonal works out as 12cm
40cm is equal to 0.4 meters, so to find the fraction of 1 meter that 40cm represents, simply divide the length in meters by 1: 0.4 meters รท 1 meter = 0.4. So, 40cm is equal to 0.4 of 1 meter.
circumference = pi*40cm
To find the area of a regular hexagon with side length of 40cm, consider that since it is regular, then it consists of 6 equilateral triangles of side 40cm. Half of each of those triangles is a right triangle. By the pythagorean theorem, we know that if the hypotenuse is 40cm, and one side is 20cm, then the other side is the square root of (40cm squared - 20cm squared) or about 34.64cm. That makes the area of each of those 12 right triangle to be about 692.8cm, so the total area of the hexagon is about 8313.8cm.
Perimeter= 2length x 2widthSince the perimeter is 40 and 2 times the width is 16, that means 2 times the length is 24. The length is 12.
First, you must find the width. Use Pythagoras' Theorem. Then, just add the lengths of the four sides, to get the perimeter.

Assuming these are the three orthogonal dimensions (length breadth and height) of a cuboid, the volume is: 1*3*40 = 120 cubic cm
Make several measures of the length and add the results together. Divide by the number of measurements taken.
The answer will depend on whether the length is the hypotenuse or one of the legs of the triangle.
You first need to find out what the pieces are. 12 mm is a measure of length. Length, by itself cannot be converted to an equivalent mass.
