Question

find the lateral surface area and total surface area of cuboid with dimensions 4.5m,3m,2m​

Answer 1

Answer:

T.S.A = 57 m²

L.S.A = 45 m²

Step-by-step explanation:

Total S.A. = 2(lb + bh + lh)

= 2( 13.5 + 6 + 9 )

= 2 × 28.5

= 57 m²

L.S.A = 2(l+b)h

= 2 ( 5 ) 4.5

= 10 × 4.5

= 45 m²

Answer 2

Answer:

LSA is 45 m²

TSA is 57 m²

Step-by-step explanation:

LSA of cuboid=2(l+b)h

=2(2+3)4.5

=2*5*4.5

=45m²

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

=2(4.5*3+3*2+2*3.5)

57 m²
