Answer 2

Answer:

Step by step explanation

given: l = 3 cm , b = 2cm and h = 1cm

to find : LSA and TSA of a cubiod

LSA of a cubiod = 2h(l+b) sq.units

= 2(3+2)

= 2(5)

= 10 sqcm

TSA of a cubiod = 2(lb+ bh+ hl) sq. units

= 2(3×2 + 2×1 +1×3)

=2( 6+ 2+ 3)

=2(11)

= 22 sq cm

therefore LSA = 10 sq cm ; TSA = 22 sq cm
