Answer 1

Answer :-

• The lateral surface area of cuboid is 130cm². [ Option. d. 130cm² ].

Step-by-step explanation :

To Find :-

• The lateral surface area of cuboid

Solution :-

Given that,

Dimensions of the cuboid = 7cm*6cm*5cm,

• Length of cuboid = 7cm
• Breadth of cuboid = 6cm
• Height of cuboid= 5cm

According the question,

The lateral surface area of cuboid is,

As we know that,

Lateral surface area of cuboid = 2 [ ( l + b ) × h ] sq. units,

Where,

• l = Length
• b = Breadth
• h = Height

=> 2 [ ( l + b ) × h ] cm²

=> 2 [ ( 7 + 6 ) × 5 ] cm²

=> 2 [ ( 13 ) × 5 ] cm²

=> 2 [ 13*5 ] cm²

=> 2 [ 60 ] cm²

=> ( 2*65 ) cm²

=> 130 cm²

• The lateral surface area of cuboid is 130cm².
