Answer 1

Answer:

lateral surface area. 4. l.b

= 4.12..10= 480

Answer 2

Answer:

QUESTION :-

find the lateral surface area and the total surface area of a cuboid whose length = 12 cm , breadth = 10 cm and height = 14 cm

ANSWER :-

Lateral surface area of the cuboid =

→ 2 (l + b) × h

→ [ 2 ( 12 + 10 ) × 14 ] cm²

→ [ 2 × 22 × 14 ] cm²

→ 616 cm²

Total surface area of the cuboid=

→ 2 ( lb + bh + hl )

→ [2(12 × 10 + 10 × 14 + 14 × 12)] cm²

→ [2(120 + 140 + 168)] cm²

→ [2 × 428] cm²

→ 856 cm²

Hence, the lateral surface area is 616 cm² and the total surface area is 856 cm²
