Which of the following has the smallest volume?
A) cube with side 5 cm
B) sphere with radius 3 cm
C) cuboid with sides 2 cm, 3 cm, 10 cm
D) cylinder with radius 2 cm and 10 cm

1.Length of each side of cube, s = 5 cmNow, volume of cube = s3 = 53 = 125 cm32.Radius of sphere, r = 3 cmvolume of sphere = 43πr3 = 43×227×33 = 113.14 cm33.Length of cuboid = 2 cmbreadth of cuboid = 3 cmheight of cuboid = 10 cmvolume = length × breadth × cuboid = 2 × 3 × 10 = 60 cm34.radius of base of cylinder, r = 2 cmheight of cylinder, h = 10 cmNow, volume of cylinder = πr2h = 227×22 × 10 = 125.71 cm3Hence the volume of the cuboid has smaller value.
