1-What are all the formulas of grade 6 mathematics?

1, triangle area = base × height ÷2. The formula s = a× h ÷ 2;

2. area of rectangle = length× width formula s = a× b;

3. The area of parallelogram = base× height formula S = a× h;

4. Sum of internal angles: sum of internal angles of triangle = 180 degrees.

5. trapezoidal area = (upper bottom+lower bottom) × height ÷2 Formula S = (a+b) H ÷ 2;

6. The surface area of a cuboid = (length× width+length× height+width× height )× 2 Formula: S = (a× b+a× c+b× c )× 2;

7. Square area = side length × side length formula S = A2

8. Surface area of cube = side length × side length× 6 Formula: S = 6a2.

9. cuboid volume = length× width× height formula: V = abh；;

10, the surface area of the cube = side length× side length× 6 formula: S = 6a2.
