Question

find the t.s.a of a cuboid with measurements 5m×4m×3m

Answer 1

friend use formula of t s a of cuboid that is 2(lb+bh+hl)
which is 2(5x4+4x3+3x5) =62m^2

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\therefore{\text{T.S.A\:of\:cuboid=94\:m}^{2}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given : }} \\ : \implies \text{Length(l) = 5 \: m} \\ \\ : \implies \text{Breadth(b) = 4\: m} \\ \\ : \implies \text{Height(h) = 3 \: m} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{T.S.A \: of \: cuboid = ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{T.S.A \: of \: cuboid} = 2(lb + bh + hl) \\ \\ : \implies \text{T.S.A \: of \: cuboid} = 2(5 \times 4 + 4\times 3+ 3 \times 5) \\ \\ : \implies \text{T.S.A \: of \: cuboid} = 2(20 + 12+ 15) \\ \\ : \implies \text{T.S.A \: of \: cuboid} = 2 \times 47 \\ \\ \green{: \implies \text{T.S.A \: of \: cuboid = 94 \:{m}}^{2} } \\ \\ \purple {\text{Some \: formula \: related \: to \: this \: topic}} \\ \pink {\circ \: \text{L.S.A\: of \: cuboid = }2(l + b) \times h} \\ \\ \pink {\circ \: \text{Volume \: of \: cuboid = }l \times b \times h}$
