Let
H= 2m= 200 cm
B= 1.25m= 125cm
L= 85 cm
Now,
Required surface area = TSA of cuboid - (Surface area of top)
Putting values:
2(LB+BH+HL) - LB
= 2(10,625+ 25,000+ 17,000) -10,625
=21,250+50,000+ 34,000 -10,625
= 94,625 cm^2
H= 2m= 200 cm
B= 1.25m= 125cm
L= 85 cm
Now,
Required surface area = TSA of cuboid - (Surface area of top)
Putting values:
2(LB+BH+HL) - LB
