Question

find lateral surface area
length 10m
breadth 35cm
height 1.2m​

Answer 1

AnSwEr -:

37.8 m^2  is the lateral surface area .

______________________________

_______________________________

LSA of cuboid -: 2h ( l + w )

H = height

L= length

W = width or breadth

_____________________________

Given ,

L = 10m

Breadth is in cm we have to convert it into m [we know 1 m = 100 cm]

B= 35 cm or 0.35 m

H = 1.2 m

LSA = 2h (l+b)

2 x 1.2 (10 + 0.5 )

= 3.6 x 10.5

37.8 m^2

_____________________________

3.8 m^2  is the lateral surface area .

Formulas for cuboid-:

LSA of cuboid -: 2h ( l + w )

T SA=2lw+2lh+2hw

Here ,

H = height

L= length

W = width or breadth

Answer 2

Answer:

lsa=2h(l+b) =2*1.2(35+10) =2.4*45=108

I hope my answer helps you☺☺
