Question

find the surface area of cuboid with dimensions as length 4 cm , breath 1.7 cm and height 2.3cm

Answer 1

HEY MATE HERE IS YOUR ANSWER

Length = 4 cm

Breadth = 1.7 cm

Height = 2.3 cm

We know that,

Total surface area of cuboid = 2(lb + bh + hl)

➡️ 2( 4 × 1.7 + 1.7 × 2.3 + 2.3 × 4)

➡️ 2(6.8 + 3.91 + 9.2)

➡️ 2(5.51)

➡️ 11.02 cm



Hope it will help you

Answer 2

$\large\mathsf\red{Dimensions \ of \ Cuboid}$

$\mathsf{Length, \ l \ = \ 4 \ cm}$

$\mathsf{Breadth, \ b \ = \ 1.7 \ cm}$

$\mathsf{Height, \ h \ = \ 2.3 \ cm}$

$\large\mathsf\purple{T.S.A. \ of \ Cuboid \ -}$

$\large\mathsf\purple{= \ 2(lb + bh + hl)}$

$\mathsf{= \ 2[(4)(1.7) + (1.7)(2.3) + (2.3)(4)]}$

$\mathsf{= \ 2(6.8 + 3.91 + 9.2)}$

$\mathsf{= \ 2 × 19.91}$

$\mathsf\blue{= \ 39.82 \ cm^2}$
