A SUITCASE WITH MEASURES 80CM ×48CM×24CM IS TO BE COVERED WIYH TARPULIN CLOTH. HOW MANY METERS OF TARPULUN WIDTH 96 CM IS REQUIRED. TO VOVER 100 SUVH SUIYCASES​

Answer 1

$Surface \: area \: of \: one \: suitcase = 2[(80 \times 48) + (48 \times 24) + (80 \times 24)] \\ = 2(3840 + 1152 + 1920) \\ = 2 \times 6912 = 13824 \: {cm}^{2}$

Surface area of 100 such suitcases= 100 x 13824

= 1382400 cm²

$∴ Length \: of \: Tarpaulin \: cloth \: required = \frac{1382400}{96} = 14400 \: cm \: = 144 \: m$

Hope It Helps :)
