    length of tank = 4m

    breadth of tank = 3m

    height of tank = 2m

    for finding the cost, we will need to find the TSA

    TSA = 2 ( lh + lb + bh )

    TSA = 2 ( 4*2 + 4*3 + 3*2 )

    TSA = 2 ( 8 + 12 + 6 )

    TSA = 16 + 24 + 12

    TSA = 52m^2

    cost for cm^2 = 50p

    cost for 0.0001 m^2 = 50p

    cost for 1m^2 = 500000p

    cost for 52m^2 = 500000*52

    cost = 2600000 paise

    Step-by-step explanation:

    total surface area=2(ab+bc+ac)

    =2(12+6+8)

    =52m²=520000cm²

    cost =50 paise per cm²

    cost of painting=520000×50

    =2600000paise=260000 rupees
