I have a question here, it's jan 2007 question no. 9 part c. I don't knw hw they got the exact value as 9 root 3. The formula is 0.5*36*sin (2pi/3), right? So hw did they get the exact value with the root? hw is the root brought here?

Remember: Sin(2π/3) = Sin(π − π/3) = Sin(π/3) = √3/2
Area = (½) * a * b * SinC
Area = ½ * 6 * 6 * Sin(2π/3)
Area = 36/2 * √3/2
Area = (36√3)/4
Area = 9√3

[cardude456]

surface area of cubiod anyone ??? HELP

Area of rectangles + area of squares

2 squares and 4 rectangles.....i think

 

[Yomna ElHabiby]

surface area of cubiod anyone ??? HELP

Area of a cuboid = 2(lw+wh+hl)
L= Length.
W = Width.
H= Height.
