How do you find the surface area of a cube?
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 lenght of one side of a cube. We have 96 = 6a2 → a2 = 16, so that’s the area of one face of the cube.
What is the formula for surface area?
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
What is the surface area of a 5 cm cube?
so 6 x 25cm^2 = 150cm^2 total surface area of cube. Originally Answered: Each sides of a cube measure 5 cm….What is the surface area to volume ratio of a 5 cm cube?
| Cube | Surface area | Surface area to volume ratio |
|---|---|---|
| micro 1 cm x 1 cm x 1 cm | 6 | 6:1 |
| macro 5 cm x 5 cm x 5 cm | 150 | 1.2:1 |
| multimicro each side made of 5 micro cubes | 750 | 6:1 |
What is the surface area of a 6 cm cube?
The surface area of the smaller cubes = 6 (12) = 6 cm2. Therefore, the surface area of 64 such cubes = 64 * 6 = 384 cm2.

What is the area of the rectangle ABCD?
Answer. Answer: Area of the rectangle ABCD is 40 sq. cm.
How do you find area example?
For example, in a rectangle we find the area by multiplying the length times the width. In the rectangle above, the area is 2×4 or 8. If you count the small squares you will find there are 8 of them.
What is the sign for area in math?
A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).
How do you calculate an uneven area?
How to use irregular area calculator?
- Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other).
- Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2.
- Step 3: Press calculate button.
- Our Formula: Area = b × h.
How do I calculate the area of a rectangle?
To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply. where A is the area, s is the length of a side, and · means multiply.
What is the formula for shapes?

|---|---|---|
| Circle | π × r2 | r = radius of the circle |
| Triangle | ½ × b × h | b = base h = height |
| Square | a2 | a = length of side |
| Rectangle | l × w | l = length w = width |
How do you find the area of a quadrangle?
If the diagonal and the length of the perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.
