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
