surface area of the wedge?

Question

a wedge ABCDEF has a perpendicular to the plane FEDC with measurements BC=5cm,CD=12cm,DE=13cm
Calculate:
(i)the length,in cm,of BD
(ii)the surface area,in cm2,of the wedge
(iii)the volume,in cm3,of the wedge
(iv)the size of angle BDC

Answer 1

BD = sqrt(5^2+12^2) = 13 cm

SA = 5*12+ 12*13+13^2+5*13= 60+156+169+65=450 cm^2

V = 5*12/2 *13 = 390 cm^3

angle BDC = arctan(5/12)

Answer 2

Give us a question to solve. Just find the area of each side and add em together.

Everytime you ask for homework help that you could obviously could do yourself, God kills a puppy.
