Answer 2

Solution -

We have,

• Length of cuboid = 80cm
• Breadth of cuboid = 80cm
• Height of cuboid = 20cm

⠀

Lateral surface area means the area of four faces of the cuboid. So, we will use the given formula

$\large{\bf{\longmapsto{\boxed{\pink{LSA = 2(l + b)h}}}}}$

⠀

Here,

• l = length
• b = breadth
• h = height

⠀

Putting the values

$\tt:\implies\: \: \: \: \: \: \: \: {LSA = 2(80 + 80) \times 20}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {LSA = 2(160) \times 20}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {LSA = 320 \times 20}$

⠀

$\frak:\implies\: \: \: \: \: \: \: \: {\purple{LSA = 6,400\: cm^2}}$

⠀
