# Cuboid

Cuboid with edge a=6 cm and body diagonal u=31 cm has volume V=900 cm3. Calculate the length of the other edges.

Result

b =  30 cm
c =  5 cm

#### Solution:

Checkout calculation with our calculator of quadratic equations.

$c=c_{2}=5 \ \text{cm} \ \\ \ \\ \text{ Correctness test: } \ \\ d=\sqrt{ a^2+b^2+c^2 }=\sqrt{ 6^2+30^2+5^2 }=31 \ \\ d=u \ \\ V_{2}=a \cdot \ b \cdot \ c=6 \cdot \ 30 \cdot \ 5=900 \ \text{cm}^3 \ \\ V_{2}=V$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
