Answer 1

Answer:

16480 cm²

Step-by-step explanation:

As we have to Find the Metal Sheet Required to make 10 Cuboidal Tin Box. For that we will find TSA of 1 Cuboidal Tin Box.

Given Dimensions Are :

Length = 20 cm

Breadth = 16 cm

Height = 14 cm

Total Surface Area of Cuboidal Box :

TSA = 2(lb + bh + hl)

TSA = 2(20 × 16 + 16 × 14 + 14 × 20)

TSA = 2(320 + 224 + 280)

TSA = 2 × 824

TSA = 1648 cm²

Total Area of Metal Sheet Required :

Total Sheet Required = TSA × Boxes

Total Sheet Required = 1648 cm² × 10

Total Sheet Required = 16480 cm²
