Calculate the ratios of surface area to volume. Which is higher? Consider the following properties of two cubes of different sizes: Cube A Cube B Length = 2 cm Length = 5 cm Surface area = 24 cm2 Surface area = 150 cm2 Volume = 8 cm3 Volume = 125 cm3 Calculate the ratios of surface area to volume. Which is higher? Cube A, surface area/volume = 8 cm3; Cube B, surface area/volume = 125 cm3; B is higher Cube A, surface area/volume = 24 cm2; Cube B, surface area/volume = 150 cm2; B is higher Cube A, surface area/volume = 8:24; Cube B, surface area/volume = 125:150; B is higher Cube A, surface area/volume = 3:1; Cube B, surface area/volume = 1.2:1; A is higher

Answer:

Cube A with ratio area/ vol  = 3 has bigger ratio than Cube B ( 1.272)

Step-by-step explanation:

Cube A length  = 2 cms   the cube has 6 faces, and each has 4 cm²

Total area = 6 * 4  = 24 cm²

Vol = 2 * 2 *2  = 8  cm³

Surface area / Volume   24/8 = 3

Cube B length  = 5 cms   the cube has 6 faces, and each has 25 cm² Total area = 6 * 25  = 150 cm²

Vol = 5 * 5 * 5 = 125 cm³

Surface area / Volume = 150/125  = 1.272
