Answer:
Step-by-step explanation:
volume of cuboid = lbh
=3x.2x.1x
volume = 10368
10368=3x.2x.1x
= 6x^3
6x^3 = 10368
x^3 = 10368/6
x^3= 1728
x = ∛1728
x = 12
length = 12*3=36
breadth = 12*3 = 24
height = 12*1 = 12
TSA of cuboid = 2(lb+bh+hl)
= 2(36*24+24*12+12*36)
=2(864+288+432)
=2*1584
= 3168
money required to polish = 0.5*3168
=Rs1584
hope you understand
