(1) a = bxh
(2) a = 1/2 bxh
(3) AB^2 = AB^2 + (AB)^2
(4) = nr^2 (circ / diam)
(5) Not 100% sure on finding perimter of cirlce
Thanks for taking the time Maze.
No I haven't learned the method of breaking it up into pieces. Could you elaborate further pls.
I'm studying Residential Drafting via correspondece, so unfortunately I do not have a teacher to refer to. Thanks again.
I'm a new student to complex maths & I'm after the formula to calculate the exterior surface area of the prism - see attached diagram.
I know formula for a surface area of triangular prism = ab + ph and cylinder = 2pir^2 + 2 pi rh. Don't know where/how to apply formula to half of these...
