Area Of A Cube Equation Math

Since there are six sides the total surface area call it sa can be found as shown below. Surface area 6 a 2 surface area 6 3 2 surface area 6 3 3. By definition all sides of a cube are equal in length so each face is a square there are six faces on a cube so its total surface area is six times the area of one of its square faces.

This means that each of the cube s six faces is a square.

Area of a cube equation math. As per the definition of the cube we know the cube consists of 6 square faces. Sa a 2 a 2 a 2 a 2 a 2 a 2 sa 6 a 2 a few examples showing how to find the surface area of a cube example 1. How to find the surface area of a cube recall that a cube has all edges the same length see cube definition. Given side of the cube a 5 cm surface area of a cube 6a 2 6 x 52 cm 2 6 x 25 cm 2 150 cm 2.

Area side 2 a 2. Let grade 6 students get accustomed to using the surface area of a cube formula sa 6s 2 where s is the side length. When all sides are of equal dimensions it becomes a cube. Either way finding the surface area and the volume require the same formulas.

What is the surface area of a cube of side 5 cm. Find the surface area if the length of one side is 3 cm. Therefore the total surface area of a cube 6 area of each side 6 a 2 6a 2 square unit. Surface area of a cube formula.

For a cube with sides of length l the surface area a 6l 2 a 6l2 area of a square a cube is made from squares and a square is a special type of rectangle. Surface area of cubes with integer side lengths easy. If one of its sides is 4 meters then this will also be the other dimension of one of its square faces so the total surface area is. The surface area of a cube formula is surface area of cube 6a2 where a is the side length of the cube.

The mathematical formula that results from this discussion is. Now we know by the formula of area of a square. Surface area 2 lh 2 lw 2 wh volume lhw these formulas will allow you to find the surface area of a cube as well as its volume and geometric relationships within the shape. The total surface area is therefore six times the area of one face.

Plug the side length which is an integer 20 and compute the surface area of each cube. Let us consider a cube whose length of the edges is a.
