Answer 2

There is 128.79 meters is required to cover 150 such suitcases.

Step-by-step explanation:

Since we have given that

Number of suitcases = 150

Dimension of suitcase = 55 cm  × 35 cm × 12 cm

Width of tarpaulin = 70 cm

We need to find the length of tarpaulin:

So, According to question, we get that

$\text{Number of suitcase}=\dfrac{\text{Surface area of suitcase}}{\text{Surface area of tarpaulin}}\\\\150=\dfrac{70\times x}{2(55\times 35+35\times 12+12\times 55)}\\\\150\times 6010=70\times x\\\\x=\dfrac{150\times 6010}{70}\\\\x=12878.57\ cm\\\\x=128.79\ m$

Hence, there is 128.79 meters is required to cover 150 such suitcases.
