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

Calculate the SA/V ratio for a cube that is 2 cm and 3 cm on each side.

Cell Size Surface Area Volume SA/V Diffusion Time

1 cm 13:44 min

2 cm 54:35 min

3 cm 1 Hr 41:24 min

The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the length of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
