Question

What is the lateral surface area of a cuboid whose length, breadth and height is 4.5 cm, 5.5 cm and 6.5 cm respectively :-​

Answer 1

Answer:

LSA = 121 cm²

Step-by-step explanation:

given a cuboid of dimension, 4.5cm x 5.5cm x 6.5cm

=> l = 4.5cm ; b = 5.5cm ; h = 6.5cm

lateral surface area of a cuboid = 2(lb+bh) sq.units or 2b(l+h) sq.units

                                                    = 2*5.5 ( 4.5+6.5) cm²

                                                    = 11 ( 11) cm²

                                                    = 121 cm²
