Question

Find the TSA and LSA of a cuboid whose length is 6cm breadrh is 5cm and height is 2cm​

Answer 1

GiveN :-

• Length of the cuboid = 6 cm

• Breadth of the cuboid = 5 cm

• Height of the cuboid = 2 cm

To FinD :-

• Total surface area of cuboid

• Lateral surface area of cuboid

SolutioN :-

$\large :\implies \boxed{\red { \bf TSA =2(LB + BH + HL)}} \\ \\ :\implies \sf TSA =2(6 \times 5 + 5 \times 2 + 2 \times 6) \\ \\ :\implies \sf TSA =2(30 + 10 + 12) \\ \\ :\implies \sf TSA =2 \times 52 \\ \\ :\implies \underline{ \boxed{ \blue{\sf TSA =104 \: {cm}^{2}}}}$

_____________________________

$\large :\implies \boxed{\red{\bf LSA =2H(L + B)}} \\ \\ :\implies \sf LSA =2 \times 2(6 + 5) \\ \\ :\implies \sf LSA =4 \times 11 \\ \\ :\implies \underline { \boxed{\blue{\sf LSA =44 \: {cm}^{2}}}}$

Answer 2

Answer:

$\huge \bold {\underline {\bf{ \tt{GiveN :-}}}}$

• Length of the cuboid = 6 cm

• Breadth of the cuboid = 5 cm

• Height of the cuboid = 2 cm

$\huge \bold {\underline {\bf{ \tt {To \: FinD :-}}}}$

• Total surface area of cuboid

• Lateral surface area of cuboid

$\huge \bold {\underline {\bf{ \tt {SolutioN :- }}}}$

$:⟹{\large{\tt{\bold{\boxed{\bf{\red{TSA=2(LB+BH+HL)}}}}}}}$

:⟹ TSA =2 ( 6 × 5 + 5 × 2 + 2 × 6 )

:⟹ TSA = 2 ( 30 + 10 + 12 )

:⟹ TSA = 2 × 52

$:⟹{\large{\tt{\bold{\boxed{\bf{\blue{TSA=104cm²}}}}}}}$
