2*(11*10 + 10*12 + 12*11) = 2*(110 + 120 + 132) = 2*362 = 724 sq cm

5cm * 5cm * 10cm = 250 cm3
V = 10cm * 6cm * 5cm = 300cm3
Fungi make their food via absorption, and a large surface area makes nutrient absorption extremely efficient.

A cylinder 10 feet high and 5 feet in radius has a surface area of 471.24ft2
5cm * 5cm * 10cm = 250 cm3
V = 10cm * 6cm * 5cm = 300cm3
A cylinder with a diameter of 1 foot and 3 feet high has a surface area of 11 square feet.
Assuming a rectangular prism. The surface area is 550 square inches.
This is not necessarily true. Only when the heal tapers will its surface area be smaller. The surface area is that which is in contact with the ground. Platform shoes are likely to have the same surface area as normal shoes, and stilettos will have a very tapered heel and therefore small surface area and great pressure per square unit)
The answer will depend on the country whose pennies you have in mind. Since you have not shared that crucial bit of information, I cannot provide a more useful answer.
High - each branch inside the lungs sub-divides many, many times. This dramatically increases the surface area in relation to the actual volume.
10 cm heels will make you just over 10cms taller.
