Find the L.S.A, T

Answer :

Given:

l = 2m, b = 3m and h = 7m


(a) LSA of cuboid = 2(lh+hb)


= 2(2(7) + 7(3))


= 2(14+21)


= 2(35) = 70m2


LSA of cuboid = 66m2


(b) TSA of cuboid = 2(lh+hb+lb)


= 2(2(7) + 7(3) + 2(3))


= 2(14+21+6)


TSA of cuboid = 82m2


(c) Volume of cuboid = l× b× h


= 2× 3× 7


Volume of cuboid = 42m3
