Question

Find the T.S.A. of a cuboid whose length 10cm. breadth 8cm. & height is 6cm.
​

Answer 1

Step-by-step explanation:

Given,

Length=10 cm;

Breadth=8 cm; &

Height=6 cm.

To Find,

The total surface area of cuboid

Solution,

Total Surface Area =2[LB+BH+LH]

                                =2[10*8+8*6+10*6]

                                =2[80+48+60]

                                =2*188

                                =376

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

$\green{\therefore{\text{T.S.A\:of\:cuboid=376\:cm}^{2}}}$

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

$\green{ \underline \bold{given : }} \\ : \implies \text{Length(l) = 10 \: cm} \\ \\ : \implies \text{Breadth(b) = 8\: cm} \\ \\ : \implies \text{Height(h) = 6 \: cm} \\ \\ \red{ \underline \bold{to \: find : }} \\ : \implies \text{T.S.A \: of \: cuboid = ? }$

• According to given question :

$\bold{as \: we \: know \: that} \\ : \implies \text{T.S.A \: of \: cuboid} = 2(lb + bh + hl) \\ \\ : \implies \text{T.S.A \: of \: cuboid} = 2(10 \times 8 + 8 \times 6 + 6 \times 10) \\ \\ : \implies \text{T.S.A \: of \: cuboid} = 2(80 + 48 + 60) \\ \\ : \implies \text{T.S.A \: of \: cuboid} = 2 \times 188 \\ \\ \green{: \implies \text{T.S.A \: of \: cuboid = 376 \:{cm}}^{2} } \\ \\ \purple {\text{some \: formula \: related \: to \: this \: topic}} \\ \pink {\circ \: \text{L.S.A\: of \: cuboid = }2(l + b) \times h} \\ \\ \pink {\circ \: \text{Volume \: of \: cuboid = }l \times b \times h}$
