Cuboid - volume, diagonals

The length of the one base edge of cuboid a is 3 cm. Body diagonal is ut=13 cm and diagonal of cuboid's baseis u1=5 cm. What is the volume of the cuboid?

Correct result:

V =  144 cm3

Solution:

a=3 cm u1=5 cm b=u12a2=5232=4 cm c=132u12=13252=12 cm V=a b c=3 4 12=144 cm3
