Answers
Answer:
First of all units change into one unit....I answer in cm.
1m = 100 cm
6m= 600cm
4.5m= 450cm
volume of cuboid= lbh
length= 600cm
breadth=450cm
height= 80cm
600*450*80 = 21,600,000 cm
Total surface area of cuboid=2 [lb+bh+hl]
2[600*450 + 450*80 + 80*600 ]
= 2 [270,000 + 36,000 + 48000]
= 2[354000]
=708,000 cm
lateral surface area of cuboid= 2[l+b] h
= 2[600+450] 80
2[1050]80
= 168,000 cm
