Cuboid

Cuboid has a surface of 516 cm2. Side a = 6 cm and b = 12 cm. How long is the side c =?

Result

c =  10.333 cm

Solution:

a=6 cm b=12 cm S=516 cm2 S=2(ab+bc+ac) c=(S/2a b)/(b+a)=(516/26 12)/(12+6)=31310.3333=10.333  cm  S2=2 (a b+b c+a c)=2 (6 12+12 10.3333+6 10.3333)=516a = 6 \ cm \ \\ b = 12 \ cm \ \\ S = 516 \ cm^2 \ \\ S = 2(ab+bc+ac) \ \\ c = (S/2 - a \cdot \ b)/(b+a) = (516/2 - 6 \cdot \ 12)/(12+6) = \dfrac{ 31 }{ 3 } \doteq 10.3333= 10.333 \ \text { cm } \ \\ S_{ 2 } = 2 \cdot \ (a \cdot \ b+b \cdot \ c+a \cdot \ c) = 2 \cdot \ (6 \cdot \ 12+12 \cdot \ 10.3333+6 \cdot \ 10.3333) = 516
