Question

find the surface area of cuboid whose length 3.2 m ;breadth=30 dm ; height=250cm

Answer 1

Answer : $\bold{Answer : 50.2 \: m^2}$

Explanation -

Given :

Length ( l ) = 3.2 m

Breadth (b) = 30 dm

(1/10 dm = 1 m)

30/10 dm = 3m

Height ( h ) = 250 cm

(1/100 cm = 1 m)

250/100 = 2.5 m

So,

Length = 3.2 m

Breadth = 3 m

Height = 2.5 m



Finding the Surface area of the cuboid -

Surface Area of the Cuboid = 2( lb + bh + hl )

$2(3.2 \times 3 + 3 \times 2.5 + 2.5 \times 3.2) \: m ^{2}$

$2(9.6 + 7.5 + 8) \: m^{2}$

$2 \times 25.1 \: m^{2}$

$50.2 \: {m}^{2}$



Hence :

$\bold{Surface \: of \: the \: cuboid \: 50.2 \: m^2}$
