Hello,
Some wires got crossed here. A cube is a solid (a 3D object), whereas a rectangle and a square are 2D figures. You cannot compare a 2D figure with a 3D figure any more than you can compare say a parking lot and a highrise building.

A rectangle is a quadrilateral (closed polygon with 4 sides). In a rectangle, opposite sides are parallel and equal in length. In a rectangle all 4 angles are equal, each measuring 90 degrees.
All this is true for a square, except that all sides are now equal. So you can say that a square is a special kind of rectangle, namely, a rectangle with equal sides.
Hope it helps.

How many squares in a rectangle has a perimeter of 40


That depends on the rectangle.
A 1x19 rectangle has 19 squares.
A 2x18 rectangle has 36 squares.
...
A 9x11 rectangle has 99 squares.
A 10x10 rectangle (a square) has 100 squares.
All of these rectangles have a perimeter of 40.

What is the greatest perimeter that a 48 meter squared rectangle could have?


Infinite.

A one meter by 48 meter rectangle has an area of 48 square meters and a perimeter of 98 meters. A one centimeter by 4800 meter rectangle has the same area and a perimeter of 9600.02 meters. A one millimeter by 48,000 meter rectangle has the same area and a perimeter of 96,000.002 meters. A rectangle one micron by 48,000,000 meters has an area of 48 square meters and a perimeter of 96,000,000.000002 meters. Keep making the rectangle skinnier and skinnier without changing the area, and the perimeter keeps getting longer and longer.

Perimeter of a rectangle


1 tile by 20 tiles - perimeter of 1+ 20 +1 + 20 = 42
2 tiles by 10 tiles - perimeter of 2 + 10 + 2 + 10 = 24
(can't make a rectangle with 3 rows)
4 tiles by 5 tiles - perimeter of 4 + 5 + 4 + 5 = 18
5 tiles by 4 tiles - perimeter of 5 + 4 + 5 + 4 = 18
(can't make a rectangle with 6, 7, 8 or 9 rows)
10 tiles by 2 tiles - perimeter of 10 + 2 + 10 + 2 = 24
20 tiles by 1 tile - perimeter of 20 + 1 + 20 + 1 = 42

So 6 different rectangles. Smallest perimeter is 18.

One cube has a face equivalent to the total area of another cube. find the ratio of their volumes?


Let the sides of the cubes be a and b,

the length of the diagonal of the cube whose side is b is given as square root(3)*b

according to the given question,

a=square root(3)*b

the volume of the cube with side a is given as

v1=a^3=(square root(3)*b)^3

and the volume of the cube with side b is

v2=b^3

then their ratio of volumes is given as

v1/v2=3*square root(3)*b^3/b^3=3*square root(3)

i.e v1:v2=3*square root(3):1

How do i do a number 'to the power of 1/2 or 2/3? cheers Brad


Power 1/2 is the same as square root: You can use the square root key to the left of the square key.
Similarly power 1/3 is the cube root. You use the [SHIFT][Square root] key sequence.
Power 2/3 is the square of the cube root, or the cube root of the square.

More generally, you can use the universal power key, marked with X with a raised white rectangle. It is between X square and log.

Ex: Calculate 15^(2/3)
15 [X with raised rectangle] 2 [/] 3 [)] [=]; the result is 6.082
The last parenthesis closes the left parenthesis introduced by the calculator.
Alternatively you can use the cube root and the x-root selections available under the MATH menu.(selections 4 and 5)

How to enter variables


Hello,

When you press the key between X^2 and log it gives you a template where you enter the base of the power (bigger rectangle) and the exponent (the smaller raised rectangle) . Using the 3 cubed exemple is not good because base and exponent are the same.

Exemple :15 cubed.
Press the key with an X with a small raised rectangle. The cursor blinks at the left side of the raised rectangle. Enter the exponent (3). Then use the left arrow to move the cursor to the base. Enter 15 and press [=]. The result is displayed as 3375 or in some other equivalent form (with a power of ten.)
Hope it helps.
