Question

(a) length = 15 cm, breadth = 8 cm, height = 5 cm
​

Answer 1

Answer:

Volume => 15 × 8 × 5

=> 600

Answer 2

${\huge{\underline{\underline{\bf{Question}}}}}$

If Length = 15 cm , breadth = 8 cm & height = 5 cm .

Find Volume , TSA & CSA .

${\huge{\underline{\underline{\bf{Answer\checkmark}}}}}$

● We have :

• Length = 15 cm
• Breadth = 8 cm
• Height = 5 cm

● Solution :

★ Volume -

$\rm \mapsto \: volume _{cubiod} = length \times breadth \times height$

$\mapsto \rm \: volume = lbh$

$\mapsto \rm \: volume = 15 \: cm \times 8 \: cm \times 5 \: cm$

$\mapsto \boxed{\rm \: volume = 600 \: {cm}^{3} }$

★ Total Surface Area (TSA) -

$\mapsto \rm \: tsa = 2(lb + bh + lh)$

$\mapsto \rm \: tsa = 2(15 \times 8 + 8 \times 5 + 15 \times 5)$

$\mapsto \rm \: tsa = 2(120 + 40 + 75) \: {cm}^{2}$

$\mapsto \rm \: tsa = 2 \times 235 \: {cm}^{2}$

$\mapsto \boxed{ \rm \: tsa = 470 \: {cm}^{2} }$

★ Curved/lateral Surface Area -

$\mapsto \rm \: csa = 2(l + b) \times h$

$\mapsto \rm \: csa = 2(15 + 8) \times 5$

$\mapsto \rm \: csa = 2 \times 23 \times 5 \: {cm}^{2}$

$\mapsto \boxed{ \rm \: csa = 230 \: {cm}^{2} }$

So ,

This is the required Answer !
