1. The formula for calculating the surface area of a cube is:

SA = length × width × number of sides (6)

Therefore, the surface area of a cube that is 1 cm on a side is 1 cm × 1 cm × 6 sides = 6 cm2

2. The formula for calculating the volume of a cube is:

V = length × width × height

Therefore, the volume of a cube that is 1 cm on each side is 1 cm × 1 cm × 1 cm = 1 cm3

3. The surface area to volume ratio is:

SA ÷ V

For a cube that is 1 cm on a side, SA/V ratio is 6 ÷ 1 = 6.

Calculate the SA/V ratio for a cube that is 3 cm on each side.

Explanation:

The question aks to calculate the SA/V ratio for a cube that is 3 cm on each side.

1. Calculate SA

The surface area of a cube, SA, is 6 times the area of a face.

The area of a face is length × width.

Then:

2. Calculate V

The volume, V, of a cube is:

Then:

3. Calculate the SA/V ratio

Divide SA by V:

That is the second option: 2 ← answer

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
