Question

the total surface area of a cuboid
having length 2 cm, breadth 3 cm
and height 5 cm is
cm^2​

Answer 1

Step-by-step explanation:

TSA=2(lb+bh+lh)

TSA=2(6+15+10)

TSA=2(31)

TSA=62 cm^2

Answer 2

★ Given:-

length(l) = 2 cm

breadth(b) = 3 cm

height(h) = 5 cm

★ To find:-

Total Surface Area

★ Solution:-

Formula used

TSA of cuboid=2(lb+bh+hl)

➟ TSA = 2(2×3+3×5+5×2)

➟ TSA = 2( 6+15+10)

➟ TSA = 2 ×31

➟ TSA = 62²

Thus the TSA of cuboid is 62 cm²

★More formulae for cuboid:-

LSA = 2 h( l + b )

Volume = ( l × b × h )

Diagonal = $\sqrt{l²+b²+h²}$
