Question

find the lsa and tsa of a cuboid whose dimensions are 22cmx12cmx7.5cm​

Answer 1

Answer:

22cm ×22cm × 7.5 = 1,980 the answer is

Answer 2

Answer :-

• TSA of Cuboid = 1038 cm²
• LSA of Cuboid = 510 cm²

Given :-

• Dimensions of Cuboid = 22 cm x 12 cm x 7.5 cm

To Find :-

• TSA of Cuboid = ?
• LSA of Cuboid = ?

Explanation :-

As we know,

$\boxed { \bf : \longrightarrow TSA \: of \: Cuboid = 2(LB + BH +HL) }}$

$\boxed { \bf : \longrightarrow LSA \: of \: Cuboid = 2H(L + B) }}$

Now Substituting the values,

$\rm : \implies TSA \: of \: Cuboid = 2(LB + BH +HL)$

$\rm \implies 2[ \: 22(12) + 12(7.5) + 7.2(22) \: ] \: cm^2$

$\rm \implies 2[ \: 264 + 90 + 165 \: ] \: cm^2$

$\rm \implies 2[519] \: cm^2$

$\red { \boxed { \bf \implies 1038 \: cm^2 }}$

$\rm : \implies LSA \: of \: Cuboid = 2H(L + B)$

$\rm \implies 2(7.5) \: [ \: 22 +12 \: ] \; cm^2$

$\rm \implies 15 \: [ \: 34 \: ] \; cm^2$

$\red { \boxed { \bf \implies 510 \; cm^2 }}$

Hence, the TSA and LSA of the cuboid are 1038 cm² and 510 cm² respectively.
