Brilio.net – The formula for the surface area of a cube is a part of a cube that is often found in mathematics problems. Therefore, before discussing the area of a cube, you should first understand what a cube means?
Referring to the Big Indonesian Dictionary, a cube means a space bounded by six rectangular areas or the familiar shape like a dice. In the field of Mathematics, a cube is a three-dimensional geometric shape bounded by six congruent square-shaped sides.
A cube has 6 sides, 12 edges, and 8 vertices. A cube is also called a regular hexagon. Apart from that, the cube is one of the Platonic shapes, namely a shape that has the same regular polygon-shaped sides.
So, so that you understand more about the area of the cube, here is an explanation of the formula for the area of the cube, complete with example questions and discussions that are easy to understand, reported by brilio.net from various sources, Monday (4/9).
Understanding the surface area of a cube.
As a three-dimensional space shape bounded by six congruent side planes. The surface area of a cube means the sum of the areas of the six square sides of the cube.
Some properties of cubes include:
– All sides of a cube have the same size and dimensions.
– All plane angles of a cube form a plane line of 90 degrees.
– Each side of the cube faces the other four sides and is the same size.
– A cube has 12 side diagonals, 4 space diagonals, and 6 rectangular diagonals.
Some cube formulas include:
– Cube surface area formula:
To calculate the surface area of a cube is:
L = 6.side.side
Where L is the surface area of the cube and 2 is the length of the side of the cube.
– Rumus volume cube:
V = s³
where V is the volume of the cube and s is the side length of the cube³.
– Cube side diagonal formula:
d = square root of 2s.
– Cube space diagonal formula:
D = akar kuadrad 3s
