MENSURATION MATHEMATICS FORMULA

A. To find Area in Mensuration 1. Area of square A=a2 2. Area of rectangle A=l*b  3. Area of right angles triangle A= (a*b)/2 4. Area of Triangle    A= (b*h)/2 5. Area of triangle with sides A=   s=a+b+c/2 6. Area of parallelogram      A=h*a 7. Area of Circle         B. To find Perimeter in Mensuration 1. Perimeter of square         P=4*a 2. Perimeter of rectangle     P=2*(a+b) 3. Perimeter of parallelogram P=2*(a+b) 4. Perimeter of circle            P=2*pi*r 5. Perimeter of triangle with sides P=a+b+c C. To find Volume of Solid Objects in Mensuration 1. Volume of Cube                 V=a3 2. Volume of Cuboids                       V=a*b*c 3. Volume of Sphere             V=4/3*pi*r3 4. Volume of right circular cylinder            V=r2h 5. Volume of right circular cone      V=r2h D. To find Surface Area of Solid Objects in Mensuration 1. Surface Area of Cube        S=6*a2 2. Surface Area of Cuboids  S= (2*a*b+2*b*c+2*a*c) 3. Surface Area of Sphere    S=4pi*r2 4. Surface Area of right circular cylinder   S=2*pi*r2 5. Surface Area of right circular cone         S=r*(r+L)         L=root(r2+h2)
