What is the surface area to volume ratio of a cube whose sides are 3 cm long?
SA = 3 cm x 3 cm x 6 = 54 cm2 Notice that the units are “square” units. VOLUME (V) is the amount of space inside an object.
What is the surface area of a 4 cm cube?
Cube has 6 faces. The surface area of a cube which has a side of 4cm is 6*4^2=6*16 cm^2.
What is the surface area of a 9 cm cube?
∴ The total surface area of cube is 486cm2.
What is the surface area of a 8 cm cube?
We can go right ahead and square the length of the side to get the area of one side of the cube, which is 8 x 8 = 64. Then we take the area of the side and multiply it by the number of sides, which is 64 x 6 = 384. Therefore, the surface area of the cube would be 384cm squared.
What is the surface area of 6cm square?
Answer: The area of the square with sides of length 6 cm is 36 cm2.
What is the surface area to volume ratio of a 2x2x2 cube?
I. INTRODUCTION
| CELL SIZE | SURFACE AREA (cm2) | SURFACE AREA – VOLUME RATIO |
|---|---|---|
| Cubic cell (2x2x2) | 2cm x 2cm x 6 =24cm2 OR, number of cm2 faces = 4 x 6 = 24 | 3 (24/8) |
| Rectangular cell (2x4x1) | 2cm x 1cm x 2 + 4cm x 1cm x 2 + 4cm x 2cm x 2 = 28 cm2 OR, number of cm2 faces = 28 | 3.5 (28/8) |
How does the surface area to volume ratio of a 1 mm cube?
The ratio decreases as the cube becomes larger. 4. How does the surface area-to-volume ratio of a 1-mm cube compare to the surface area-to-volume ratio of a 3-mm cube? The ratio decreases as the cube becomes larger.
Is a large surface area to volume ratio good?
In fact, increasing the size of the cell has a much greater effect on the cells volume than it does on its surface area. Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.
What is the relationship between size and surface area of a cube?
As the cube gets bigger, the volume increases much more rapidly than the surface area, because the volume increases as the cube of the linear dimension, but the surface area increases as the square. This relationship applies, not just to cubes, but to spheres and any other fixed shape.
What is the normal cell?
These ‘normal’ cells act as the body’s basic building blocks and possess specific characteristics that enable them to maintain correct functioning of tissues, organs, and organ systems.
