# What is the surface of a 3 inch cube?

## What is the surface of a 3 inch cube?

Correct answer: Explanation: 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.

How do you find surface area?

The total surface area is calculated by adding all the areas on the surface: the areas of the base, top, and lateral surfaces (sides) of the object. This is done using different area formulas and measured in square units. Volume is the amount of space that a three dimensional object takes up.

What is the surface area of a cube 6x6x6?

36
Mathematical examples

6 6×6 36
8 8×8 64
12 12×12 144
20 20×20 400

### How many surface are there in a cube?

six
A cube has six flat faces, or surfaces. Each face of a cube is shaped like a square. The sides of each face are called edges. A cube has 12 edges.

What is the edge length of a cube?

The volume of a cube is length x width x height. Since it’s a cube, though, the length, width, and height are all equal, and equivalent to the length of one edge of the cube. Therefore, to find the lenght of an edge of the cube, just find the cube root of the volume. In this case, the cube root of 512 is equal to 8.

What is the surface area of a 4 cm cube?

96cm2
Once you do this you will find that a 4cm Cube has a total surface area of 96cm2 .

#### How do you find the surface area or volume?

How do I find the surface area of a square?

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

What is the surface area of 1x1x1?

6
The surface area is 6 (6 sides, each 1×1). The volume is 1 (1x1x1). For a cube of size 2: The surface area is 24 (6 sides, each 2×2).

## What is lateral surface area of cube?

The lateral surface area (LSA) of the cube = sum of areas of all 4 side faces. ⇒ LSA of cube = x2 + x2 + x2 + x2 = 4×2. Thus, the formula to find the lateral area of a cube is, LSA = 4×2.

How to calculate the surface area of a cube?

Cube The surface area of a cube can be calculated by summing the total areas of its six square faces: SA = 6a 2 where a is the edge length

How many faces are there in a cube?

Recall that a cube has all edges the same length (See Cube definition). This means that each of the cube’s six faces is a square. The total surface area is therefore six times the area of one face.

### Which is the best example of a cube?

One of the popular examples of a cube is a Rubik’s cube. You will also get many examples in real life, such as carton boxes, storage trunks, etc. So whenever we think to keep such objects in a space or area, we need to know the surface area to find a suitable place for that object.

What’s the difference between a cuboid and a cube?

Although cuboid also looks the same as a cube, the difference between cube and cuboid is cuboid has only its parallel sides equal whereas a cube has al its sides equal. A cube consists of ‘n’ number of square units. Hence the space covered by these square units on the surface of the cube is the surface area.
