Cuboid - volume and areas

The cuboid has a volume of 250 cm3, a surface of 250 cm2, and one side 5 cm long. How do I calculate the remaining sides?

Correct answer:

b =  10 cm
c =  5 cm

Step-by-step explanation:

V=250 cm3 S=250 cm2 a=5 m  V = abc  S = 2(ab+bc+ac) 50 = bc  125 = 5b + bc + 5c c = 50/b  125 = 5b + 50 + 5 50/b 125b=5b2+50b+5 50  125b=5b2+50b+5 50 5b2+75b250=0 5b275b+250=0 5 ...  prime number 75=352 250=253 GCD(5,75,250)=5  b215b+50=0  p=1;q=15;r=50 D=q24pr=1524150=25 D>0  b1,2=2pq±D=215±25 b1,2=215±5 b1,2=7.5±2.5 b1=10 b2=5  b=b1=10=10 cm

Our quadratic equation calculator calculates it.

c=b2=5=5 cm
