Question

total surface area of the cuboid whose length = 27.8 , breadth = 22.3, height =1.2​

Answer 1

Answer:

Given that l=20cm, b=12cm, h=9cm

∴T.S.A=2(lb+bh+lh)

=2[(20×12)+(12×9)+(20×9)]

=2(240+108+180)

=2×528

∴T.S.A=1056cm

Answer 2

Answer:

1360.12 is a TSA of cuboid

Step-by-step explanation:

TSA= 2(lb+bh+hl)

=2(27.8*22.3+22.3*1.2+1.2*27.8)

=2(619.94+26.76+33.36)

=2(680.06)

=1360.12
