Hey there!
l = 18 cm.
b = 10cm .
h = 8cm .
Total surface area = 2 ( 18*10 + 10*8 + 8*18) = 2 ( 180 + 80 + 144) = 2 ( 404) = 808cm² .
l = 18 cm.
b = 10cm .
h = 8cm .
Total surface area = 2 ( 18*10 + 10*8 + 8*18) = 2 ( 180 + 80 + 144) = 2 ( 404) = 808cm² .
lenght 18 cm , breath 10 cm and height 8 cm
it's a cuboid or cube tell me
cuboide
2 ( lb + bh + hl )
2 ( lb + bh + lh )
2 (lb+bh+lh) cuboid
2(lb+bh+lh)

TSA= 2(lb+bh+hl) square unit
=2(18*10+10*8+8*18)
=2(180+80+144)
=2*404
=808cm^2
=2(18*10+10*8+8*18)
=2(180+80+144)
=2*404
=808cm^2
that's what I said
why did u multiply with 2?
2 (lb+bh+hl)=808
we have to multiply to get ans
well explained
with formula
pllzz explain it brief
808 cm square is the answer
how 808 explain me
