You have a box measuring (in inches) 9 (length) x 3 (width) x 2 (depth) = 54 cubic inches. But you want the surface area. One top, one bottom two sides, two ends.
Top and bottom are (9x3)x2 = 54 square inches.
Two long sides are (9x2)x2 = 36 square inches.
Two ends are (3x2)x2 = 12 square inches.
54 + 36 + 12 = 102 square inches.

What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
How can you obtain a cell's ratio of surface area to volume?
To obtain the ratio of surface area to volume, divide the surface area by the volume.
Why sphere has minimum surface area for given volume?
The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . . If it is known is N-face surface area of ​​the body, there are N +1 is smaller the surface area of ​​the surface When N tends to infinity for a long time, Serve the sphere surface. ------mecose
What is the mathematical name for surface area?
it is still surface area
What is ratio of surface area to volume?
surface area/ volume. wider range of surface area to volume is better for cells.
