Expert Answer:

To find the volume we need to find the measurements of sides first. Let the sides be = x,y and z

According to the problem :

xy = 120 ⇒ y = 120/x

yz = 60

zx = 72

Put the value of y =120/x in second equation we get 120z/x = 60 or z = x/2. Now put this value in 3rd equation we get

x2/2 = 72

x2 = 144 or x = 12cm

y = 10cm

z = 6cm

Now the volume of given cuboid is = xyz = 12 x 10 x 6 = 720cm3
