Question
A cube of volume 768 cm³ is molded into a cuboid whose
length, width, and height are in the ratio 2: 2: 3. Find the length of the cuboid.Solution
Ratio of length, width, and height =2:2:3 Let length =2x, width =2x, height =3x. Volume of cuboid =l×b×h 3x ×2x×2x =768 12x3 =768 x3 =64 x = 4cm now the length of the cuboid =2×4 =8cm.
