All Math Formula on Mensuration
Mensuration● Prism:(i) Area of the lateral faces of a right prism = perimeter of the base × height.(ii) Area of the whole surface of a right prism = Area of the lateral faces + 2 × area of the base. (iii) Volume of a right prism = area of the base × height. ● Pyramid:(i) Area of the lateral faces of a right pyramid = (1/2) × perimeter of the base x slant height.(ii) Area of whole surface of a right pyramid = area of the lateral faces + area of the base. (iii) Volume of a right pyramid = (1/3) × area of the base × height. ● Tetrahedron:If a be the length of an edge of a regular tetrahedron then(i) the area of its slant sides = (3√3/4)a^{2} sq. units; (ii) the area of its whole surface = √3a^{2} sq. units (iii) the volume of the tetrahedron = (√3/12)a^{3} cu. units.● Formula
