Question

Lengthy 48cm Breadth 6dm
Height 1m

Answer 1

Answer:

Length=48cm=0.48m

Breadth=6dm=0.6m

Height=1m

LSA=2(length+Breadth)×height

= 2(0.48+0.6)×1

=2×1.08

=2.16m²

TSA=2(length×breadth+ breadth×height + height×length)

= 2(0.48×0.6+0.6×1+1×0.48)

=2(0.288+0.6+0.48)

=2×1.368

=2.736m²
