Answer:

TSA = 603 square centimetre

CSA = 243 square centimetre

Step-by-step explanation:

Given :-

Length = 15 cm

Breadth = 12 cm

Height = 4.5 cm

According to question:-

CSA of cuboid - 2h(l+b)

= 2 x 4.5 ( 15 + 12 )

= 9 (27)

= 243 square centimetre

TSA of cuboid = 2 (lb + bh + hl)

= 2 { ( 15 x 12 ) + ( 12 x 4.5 ) + ( 15 x 4.5 )

= 2 { (180) + (54) + (67.5) }

= 2 (301.5)

= 603 square centimetre
