8.

using 27 small cubes, produce a structure that has a large surface area but that is

at most 5 cm long in any one dimension.

sa=weh

v=bh

what is the surface area of the structure?

what is the volume of the structure?

what is the surface area to volume ratio?

1. the surface area of a cubic structure is = 6 x s x s =  6 x 5 x 5 =150cm²

2. volume of a cubic structure = s³ = 5x5x5 = 125cm³

3. surface area to volume ratio = Surface area / volume

= 150/125 = 1.2

Explanation:

using 27 small cubes to form a structure will be arrange in 3 cubes (length) by 3 cubes (bredth) by 3 cubes(height)

a cubes has the same side all through,

A cubical structure having 5cm length in any of its sides

s = 5cm (length of one side of the structure)

1. the surface area of a cubic structure is = 6 x s x s =  6 x 5 x 5 =150cm²

2. volume of a cubic structure = s³ = 5x5x5 = 125cm³

3. surface area to volume ratio = Surface area / volume

= 150/125 = 1.2

the correct answer would be 6 feet.

the answer is d. chordata
