# Find the L.S.A, T.S.A and volume of the cuboids having the length, breadth and height

respectively as

20 m, 12 m, 8 m

Answer :

Given:

l = 20m, b = 12m and h = 8m

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

= 2(20(8) + 8(12))

= 2(160+96)

= 2(256) = 512m^{2}

⇒ LSA of cuboid = 512m^{2}

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

= 2(20(8) + 8(12) + 20(12))

= 2(160+96+240)

⇒ TSA of cuboid = 992m^{2}

(c) Volume of cuboid = l× b× h

= 20× 12× 8

⇒ Volume of cuboid = 1920m^{3}
