2 litres = 2000 cm3
The cross-sectional area of the vase is 11*11 cm2 = 121 cm2
So height = 2000/121 = 16.5289 cm (to 4 dp).
The ratio of 115 to 30 is ( 23/6 ).
Depends on the type of piano I guess. Most keyboards are rectangle shaped, there are rectangle/square shaped grand pianos but they are not common, most uprights are rectangle.
A dollar bill is truly shaped like a rectangle.
Rectangle dumby
Well, it depends on the area of the shape you are trying to find, if its: square: length times width triangle: base times height divided by 2 circle: 3.14 times radius squared trapezoid: base 1 plus base 2 times height divided by 2 A U shaped figure is probably half of a circle and a rectangle. The diameter of the circle is the same as the width of the rectangle.

Only a rectangle.

It depends on the exact shape. For a square or rectangle, it would be length times width times height.

It can be a cube or a cuboid...
Perimeter of a rectangle = 2*(H+W) = 2*(11+22) = 2*33 = 66 inches.
