8. Write the formula for LSA, TSA and volume of right prism and right
pyramid
Answers
Step-by-step explanation:
right prism
area of the side faces (i.e., lateral surfaces) of a right prism
area of the side faces (i.e., lateral surfaces) of a right prism= ah + bh + ch + ........
area of the side faces (i.e., lateral surfaces) of a right prism= ah + bh + ch + ........= (a + b + c + ....... ) ∙ h
area of the side faces (i.e., lateral surfaces) of a right prism= ah + bh + ch + ........= (a + b + c + ....... ) ∙ h= perimeter of the base × height;
area of the side faces (i.e., lateral surfaces) of a right prism= ah + bh + ch + ........= (a + b + c + ....... ) ∙ h= perimeter of the base × height;(ii) area of total surfaces of a right prism
area of the side faces (i.e., lateral surfaces) of a right prism= ah + bh + ch + ........= (a + b + c + ....... ) ∙ h= perimeter of the base × height;(ii) area of total surfaces of a right prism= area of its side faces + 2 × area of its base
area of the side faces (i.e., lateral surfaces) of a right prism= ah + bh + ch + ........= (a + b + c + ....... ) ∙ h= perimeter of the base × height;(ii) area of total surfaces of a right prism= area of its side faces + 2 × area of its base(iii) volume of a right prism = ( area of base ) × (height).
right pyramid
total surface area of a regular pyramid is T.S.A.=12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
