A water tank of dimensions 2m * 3m * 1.5m is to be painted leaving its base. Find the total cost of painting the tank if rate of painting = ₹20/m2.

The formulas for cube and cuboid shapes are based on their surface areas, lateral surface areas and volume.

Cube	Cuboid
Total Surface Area = 6(side)2	Total Surface area = 2 (length × breadth + breadth × height + length × height)
Lateral Surface Area = 4 (Side)2	Lateral Surface area = 2 height(length + breadth)
Volume of cube = (Side)3	Volume of the cuboid = (length × breadth × height)
Diagonal of a cube = √3(side)	Diagonal of the cuboid =√( length2 + breadth2 +height2)
Perimeter of cube = 12 × side	Perimeter of cuboid = 4 (length + breadth + height)
