Question

total surface area of cuboid ki practical ka procedure kya hoga​

Answer 1

Hey

2(lb+bh+hl)..........

Answer 2

Hello ,

Lateral surface area of a prism is =. perimeter of base x height

Total surface area of prism = lateral surface area + 2(area of base)

Since cuboid is a rectangular prism the above mentioned formula is suitable for it .

Therefore , lateral surface area of cuboid is : (perimeter of base) (height)

= 2(l+b)(ht.)
=2(lh + bh)

Total surface area of cuboid =
Lateral surface area + 2(area of base)

= 2(lh+bh) + 2(lb)
=2(lh + bh + lb)
