Question

Find LSA and TSA of cuboid length equal to 8.2 m, breadth equal to 5.3 m height equal to 2.6 m

Answer 1

Given

Find LSA and TSA of cuboid length is 8.2 m, breadth is 5.3 m and height is 2.6 m

Solution

Cuboid dimensions

• Length = 8.2 m
• Breadth = 5.3 m
• Height = 2.6

★ Lateral surface area of cuboid ★

→ 2(l + b)h

→ 2(8.2 + 5.3)2.6

→ 2 × 13.5 × 2.6

→ 70.2 m²

Hence, Lateral surface area of cuboid is 70.2m²

★ Total surface area of cuboid ★

→ 2(lb + bh + lh)

→ 2(8.2*5.3 + 5.3*2.6 + 8.2*2.6)

→ 2(43.46 + 13.78 + 21.32)

→ 78.56 m²

Hence, Total surface area of cuboid is 78.56m²

Some Formulae

• Volume of cuboid = l*b*h
• Volume of cube = a³
• LSA of cube = 4a²
• TSA of cube = 6a²

━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\longmapsto\tt{Length(l)=8.2m}$

$\longmapsto\tt{Breadth(b)=5.3m}$

$\longmapsto\tt{Height(h)=2.6m}$

★For Lateral Surface Area :-

➥Using Formula : -

$\longmapsto\tt{\small{\boxed{\bold{\bold{\red{\sf{L.S.A\:of\:Cuboid=2(l+b)h}}}}}}}$

➥Putting Values : -

$\longmapsto\tt{2\times{(8.2+5.3)}\times{(2.6)}}$

$\longmapsto\tt{2\times{(13.5)(2.6)}}$

$\longmapsto\tt{27\times{(2.6)}}$

$\longmapsto\tt\bold{{70.2m}^{2}}$

★For Total Surface Area :-

➥Using Formula : -

$\longmapsto\tt{\small{\boxed{\bold{\bold{\orange{\sf{T.S.A\:of\:Cuboid=2(lb+bh+hl)}}}}}}}$

➥Putting Values : -

$\longmapsto\tt{2(8.2\times{5.3}+5.3\times{2.6}+2.6\times{8.2})}$

$\longmapsto\tt{2(43.46+13.78+21.32)}$

$\longmapsto\tt{2(78.56)}$

$\longmapsto\tt\bold{{157.12m}^{2}}$
