Step-by-step explanation:

rectangular box is cubiodal in shape .

the TSA of cuboid is given by the expression, 2(lb+bh+hl)

here l= 100, b=60, h=40

TSA= Surface to be painted.

TSA=2(100*60+60*40+40*100)

=2(6000+2400+4000)

= 2(12400)

= 24800cm^2 and Rs.

Volume = l*b*h

=100*60*40

=240000cm^3.
