Given :
 Cuboid
Length (l)= 15cm,
Breadth (b)= 10cm ,
Height (h)= 3.5cm.

Cone (3)
Radius (r) = 0.5cm ,
depth = height of the cone(h) = 1.4cm.

Required to solve : Volume of the entire stand = ?
Volume of the entire stand = Volume of the cuboid - 3*Volume of the cone.
=>(l*b*h) - 3*[1/3*pi* r^2* h]
=>(15*10*3.5) - 3*[1/3* 22/7* 0.5* 0.5* 1.4]
=>525 - 3*[1/3* 22* 0.050]
=>525 - 3*[1/3* 1.1
=>525 - 3/3* 1.1
=>525 - 1* 1.1
=>525 - 1.1 = 523.9 cu.cm
