Question

The lateral surface area of a cuboid whose length is 5 m, breadth is 4 m and height is 2 m is _ m^2​

Answer 1

Answer:

36m^2

Step-by-step explanation:

CSA of cuboid is 2h(l+b)

Given,

h = 2m

l = 5m

b = 4m

CSA of Cuboid = 2×2(5+4)

= 4×9

= 36m^2

Answer 2

Given

• Length of a Cuboid = 5m
• Breadth of a Cuboid = 4m
• Height of a Cuboid = 2m

⠀

To find

• Lateral surface area of the cuboid.

⠀

Solution

• Length, breadth and the height of the cuboid is given in the question.
• By using Formula

$\: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt{\bigstar{L.S.A_{(Cuboid)} = 2h(l + b){\bigstar}}}}$

⠀

Here,

• l = 5m
• b = 4m
• h = 2m

⠀

★ Putting the values

$\large{\tt{\longmapsto{L.S.A = 2(2)[5 + 4]}}}$

⠀

$\large{\tt{\longmapsto{L.S.A = 4 \times 9}}}$

⠀

$\large{\bf{\longmapsto{L.S.A = 36m^2}}}$

⠀

Hence,

• Lateral surface area of the Cuboid is 36m².

⠀

$\large\bf{\underline{\orange{Answer}}}$

The lateral surface area of a cuboid whose length is 5 m, breadth is 4 m and height is 2 m is 36 m².
